This proposed Phase II SBIR would realize a prototype of an offset Gregorian antenna design that will be delivered to NASA for integration in the D3R GPM ground validation radar system, for which RSS is currently fabricating the radar transceiver through a Phase III project. During the Phase I effort for this antenna system, Remote Sensing Solutions developed a design for a novel dual-wavelength Ku/Ka-band radar remote sensing antenna system with high integrated cross-polarization isolation (> 30 dB) and low sidelobes (< -25 dB). The design provides high gain (< 1 deg beamwidth) and matched antenna patterns in a rugged mechanical configuration that is transportable in a standard sea-container. The primary innovations realized in the Phase I design that would be implemented in the Phase II effort include: an ultra-low cross-pol reflector, a rugged compact feed with very low cross-polarization supporting multiple polarizations at Ku and Ka-band and a robust mechanical structure to meet the antenna electrical tolerances over a wide range of environmental conditions.

This proposal presents the Ka-band SWOT Phenomenology Airborne Radar (KaSPAR) to support the surface water ocean topography (SWOT) mission for science and algorithm development and calibration and validation. KaSPAR is a modular system with multiple temporal and cross-track baselines to fully characterize the scattering and statistics expected from SWOT, provide data for developing classification algorithms, and understanding instrument performance and limitations over the vast variety of scenes that SWOT will encounter (ie sea-ice, vegetation covered water, frozen/partially frozen rivers etc). Furthermore a wide-swath (>5km) high-accuracy elevation mapping capability provides the necessary framework to translate traditional point or profile calibration/validation measurements to the spatial framework that SWOT will measure. Beyond SWOT, KaSPAR's unique 4D imaging capability (2D intensity, elevation and velocity mapping) can be uniquely applied to topography applications, local water resource management and monitoring, weather reconnaissance (e.g. floods & storm surge), electronic vision applications and much more. The Phase II activities will build out a complete multichannel radar system to realize the potential of KaSPAR. Key developments include the highly phase-stable high-bandwidth receivers, low-sidelobe antennas and integration with a high power (40W) solid-state power amplifier. The modular, compact design will be compatible between platforms and is directly compatible without modification with two NASA King Air aircraft. Long-term KaSPAR is designed to support unpressurized high altitude operations.

Severe weather impacts our daily lives, society and the world economy. From an average of $10B annual loss due to tropical cyclones since 1900 to $200B in the commercial shipping industry, which is threatened by severe ocean storms to the hundreds of lives and assets lost in the $20B recreational boating industry. In these cases and many more, accurate now casting and forecasting could prevent these losses and reduce risks. A key observation to improve our knowledge of the weather is the ocean surface vector wind. The technology and product developed through this Phase II project will overcome current technology gaps preventing real-time measurements and mapping of ocean vector winds as well as the three-dimensional atmospheric winds within tropical cyclones and severe ocean storm environments. Specifically, this effort focused on designing a compact single aperture antenna that provides high resolution wide swath mapping of the atmosphere and ocean surface. Combined with the Advanced Wind and Rain Airborne Profiler (AWRAP) system, it would provide unprecedented airborne observational capability for tropical cyclones and severe ocean storm environments and imaging capabilities for search and rescue and homeland defense applications.

Severe weather impacts our daily lives, society and nation’s economy. From an average of $10B (2005 dollars) annual loss due to tropical cyclones since 1900 to $200B in the commercial shipping industry that is threatened by severe ocean storms to the hundreds of lives and assets being lost in the $20B recreational boating industry. In these cases and many more, accurate now-casting and forecasting could prevent these losses and reduce risks. Key observation to improve our knowledge of the weather is the ocean vector wind. NOAA is embarking on an ambitious but needed effort to launch a new satellite-based instrument called the Dual Frequency Scatterometer (DFS) that will provide accurate global mapping of the ocean vector wind in a timely manner. The Advance Wind and Rain Airborne Profiler (AWRAP) can play a pivotal role for this mission by providing critical measurements to improve the geophysical model function that DFS will relay to estimate the winds. However, AWRAP requires a novel antenna to collect dual polarized, dual wavelength measurements. This proposed Phase I study will develop a single aperture, narrow beam C/Ku-band polarimetric antenna for AWRAP that will enable the acquisition of the necessary measurements from the NOAA WP-3D aircraft.

Future space-borne cloud radars will require significant technical innovations for improving remote sensing of the Earth's atmosphere and that of other planetary bodies such as Venus and Saturn's moon Titan, which have significant cloud cover. One critical innovation required is a pulse compression scheme at W-band (95 GHz) with ultra-low range sidelobe levels - on the order of 90 dB. The current space-borne cloud radar flying on CloudSat is an outstanding technical achievement but lacks sensitivity to weakly reflecting low altitude clouds. Because these clouds play a significant role in modulation the Earth's radiation budget follow-on missions will have to address this limitation. Pulse compression (coded) waveforms can maximize transmitter duty cycle usage and thus system sensitivity. However, the reflection from the Earth's surface can easily mask the cloud signal via the coded waveforms range sidelobe response. The requirement for detecting these clouds from space is severe and significant innovations are required to meet them. The proposed research addresses this requirement and is supported by staff who have significant experience in MMW system development, having built and flown the first airborne cloud radar utilizing FM chirp pulse compression.

This proposal introduces an innovative sensor to advance ground collision avoidance for UAS platforms by providing real-time height maps for hazard anomaly detection. This sensor will also provide enhanced vision to overcome reduced visibility in fog, drizzle and light rain and the detection of hazards/obstacles on runways for landing and takeoff applications. Specifically, this effort will build upon a developing synthetic vision system for landing piloted aircraft to: 1) customize the design and feasibility for targeted unpiloted autonomous systems (UAS), and 2) incorporate interferometry for terrain mapping and hazard detection. Dubbed "PathIn", the proposed sensor is comprised of a Ka-band digitally beamformed (DBF) radar interferometer that will provide a real-time data interface for ground-collision avoidance systems. The proposed effort is aligned with the effort to integrate UAS into the National Airspace (NAS). The Phase II will realize a prototype of the PathIn sensor, leveraging our extensive radar, interferometry and DBF experience and key technology capabilities. In particular a FPGA-based digital receiver system will be extended for real-time beamforming and interferometry. At the end of the Phase II, a technology readiness level of 5 will be achieved.

Remote Sensing Solutions proposes to develop the Network-based Parallel Retrieval Onboard Computing Environment for Sensor Systems (nPROCESS) for deployment on NASA's unmanned aircraft systems (UAS). The nPROCESS will provide a compact, efficient, reconfigurable computing environment that will achieve unparalleled real-time data processing, acquisition and distribution to provide new observations and improved sensitivity; provide a test-bed for measurement and algorithm development and testing for future mission risk reduction and demonstration; produce critical information for real-time decision making; and facilitate a path to reduce risks and installation / operational costs for deployment of new and existing sensors on NASA UAS platforms. The proposed innovations to realize nPROCESS are: (1) reconfigurable, object orientated system architecture that will provides far greater customization and expansion, (2) modularity at the hardware, firmware and software levels to adapt to the sensors needs at minimum cost and (3) high fidelity parallel processing and data distribution capabilities. Deployed with the HIWRAP on the NASA Global Hawk, nPROCESS will provide higher quality and real-time mapping of the three-dimensional wind profiles, ocean vector surface maps and precipitation winds within tropical cyclones.

The Phase 1 effort will assess the PathIn performance for sample UAS flight scenarios over variable terrain using a high-fidelity point target simulator to provide synthetic digital surface maps and obstacle detections. This will demonstrate the potential of the PathIn as a technology that can contribute toward safe UAS operation in the NAS and in the terminal area.In Phase II we will realize a prototype of the PathIn sensor, leveraging our extensive radar, interferometry and DBF experience and key technology capabilities.

This proposal discusses the development and demonstration of a swath-based airborne instrument suite intended as a calibration and validation with relevance to the ICESat II, SWOT and CryoSAT II missions. In particular our innovation will leverage prior NASA developments to focus on system miniaturization and increased performance. It will also support NASA's airborne science missions by utilizing long-endurance unmanned aircraft such as the Ikhana or the Global Hawk. These platforms become directly relevant due to the often remote nature of regions of interest, particularly as one considers the cryosphere. The Phase I will result in a system design that can be realized in a Phase II effort. During the Phase I, measurement requirements will be revisited and key technologies will be identified and incorporated where advantageous into a revised design. Data volume and system automation will be specifically evaluated and a plan for on-board data storage and compression/processing will be proposed. An accommodation feasibility study for the Ikhana will be evaluated. The Phase II effort will realize a prototype of this sensor. At the end of the Phase I, a technology readiness level of 3 will be achieved.
