A SAR system with a single aperture that simultaneously transmits at a high and low frequency provides the distinct advantages of each individual frequency band, and the added benefit of having a collocated aperture. In this paper, the design of the multi-band SlimSAR and the unique multi-frequency antenna are presented. © 2011 IEEE.

Rabies virus is an important causative agent of disease resulting in an acute infection of the nervous system and death. Although curable if treated in a timely manner, rabies remains a serious public health issue in developing countries, and the indigenous threat of rabies continues in developed countries because of wildlife reservoirs. Control of rabies in wildlife is still an important challenge for governmental authorities.There are a number of rabies vaccines commercially available for control of wildlife rabies infection. However, the vaccines currently distributed to wildlife do not effectively immunize all at-risk species, particularly skunks. A replication competent recombinant adenovirus expressing rabies glycoprotein (AdRG1.3) has shown the most promising results in laboratory trials. The adenovirus vectored vaccine is manufactured using HEK 293 cells.This study describes the successful scale-up of AdRG1.3 adenovirus production from 1 to 500. L and the manufacturing of large quantities of bulk material required for field trials to demonstrate efficacy of this new candidate vaccine. The production process was streamlined by eliminating a medium replacement step prior to infection and the culture titer was increased by over 2 fold through optimization of cell culture medium. These improvements produced a more robust and cost-effective process that facilitates industrialization and commercialization. Over 17,000. L of AdRG1.3 adenovirus cultures were manufactured to support extensive field trials. AdRG1.3 adenovirus is formulated and packaged into baits by Artemis Technologies Inc. using proprietary technology. Field trials of AdRG1.3 rabies vaccine baits have been conducted in several Canadian provinces including Ontario, Quebec and New Brunswick. The results from field trials over the period 2006-2009 demonstrated superiority of the new vaccine over other licensed vaccines in immunizing wild animals that were previously difficult to vaccinate. © 2011 .

The SlimSAR is a flexible, multi-frequency band, multi-mode synthetic aperture radar system with options suitable for operation on aircraft across a wide range of size and capabilities. From small unmanned aircraft flying at low altitude and covering a small area, to large aircraft covering very wide swaths, the SlimSAR has the versatility to perform in any mission scenario. One application is that of disaster monitoring, and the SlimSAR has shown its capabilities imaging the aftermath of Hurricane Sandy in 2012. © 2013 IEICE.

For multi-pass SAR, a number of applications require precise duplication of the aircraft path. This paper presents the Dragonfly system, which provides a real-time display of the desired flight line from the point of view of the aircraft location. The pilot, following a path on Dragonfly, can easily repeat flight lines and circles with a good degree of precision. We also examine the experimental performance of the Dragonfly system over a series of repeated flight lines while collecting SAR data. The theoretical effects of sub-optimal flight line repetition on multi-pass SAR performance are evaluated for coherent change detection (CCD) and multi-pass interferometry (InSAR) and compared to experimental results. © 2012 IEEE.

The SlimSAR is a small, low-cost, Synthetic Aperture Radar (SAR) and represents a new advancement in high-performance SAR. ARTEMIS employed a unique design methodology in designing the SlimSAR that exploits previous developments. The system is designed to be smaller, lighter, and more flexible while consuming less power than typical SAR systems. The system consists of an L-band core and frequency block converters and is very suitable for use on a number of small UAS's. Both linear-frequency-modulated continuous-wave (LFM-CW) and pulsed modes have been tested. The LFM-CW operation achieves high signal-to-noise ratio while transmitting with less peak power than a comparable pulsed system. The flexible control software allows us to change the radar parameters in flight. The system has a built-in high quality GPS/IMU motion measurement solution and can also be packaged with a small data link and a gimbal for high frequency antennas. Multi-frequency SAR provides day and night imaging through smoke, dust, rain, and clouds with the advantages of additional capabilities at different frequencies (i.e. dry ground and foliage penetration at low frequencies, and change detection at high frequencies.). © 2010 SPIE.

This paper presents ARTEMIS, Inc.'s approach to development of end-to-end synthetic aperture radar systems for multiple applications and platforms. The flexible design of the radar and the image processing tools facilitates their inclusion in a variety of application-specific end-to-end systems. Any given application comes with certain requirements that must be met in order to achieve success. A concept of operation is defined which states how the technology is used to meet the requirements of the application. This drives the design decisions. Key to adapting our system to multiple applications is the flexible SlimSAR radar system, which is programmable on-the-fly to meet the imaging requirements of a wide range of altitudes, swath-widths, and platform velocities. The processing software can be used for real-time imagery production or post-flight processing. The ground station is adaptable, and the radar controls can be run by an operator on the ground, on-board the aircraft, or even automated as part of the aircraft autopilot controls. System integration takes the whole operation into account, seeking to flawlessly work with data links and on-board data storage, aircraft and payload control systems, mission planning, and image processing and exploitation. Examples of applications are presented including using a small unmanned aircraft at low altitude with a line of sight data link, a long-endurance UAV maritime surveillance mission with on-board processing, and a manned ground moving target indicator application with the radar using multiple receive channels. © 2012 SPIE.

In July 2015, a series of Synthetic Aperture Radar (SAR) collections were made near Lake City, Colorado over the Slumgullion Earthflow in order to demonstrate the feasibility of detecting the landslide motion over a short period of time. The Slumgullion Earthflow is a slow moving landslide that moves downhill at a rate of about 23 feet per year. The ARTEMIS SlimSAR, a compact, modular, multi-frequency radar was installed on a Cessna 206 and was used to collect SAR data of the landslide at L-band and at X-band. At both frequencies, antennas were installed in cross-Track configuration for cross-Track interferometry. Data was collected on July 3, 7, and 10 and processed using the time-domain backprojection algorithm. High-quality digital elevation map data was generated from the SAR imagery and was used in reprocessing the radar data, projecting it onto the SAR-derived surface map. The data from each day was then compared, providing measurements of the shift in the slide. The phase change shown in the differential interferograms shows change from day to day due to the physical shift in the earthflow itself. The shifting earthflow is clearly distinct from the non-shifting ground around it in the interferograms created from the SAR imagery. © 2016 IEEE.
