A collaboration between research engineers at Solid State Scientific Corporation and the University of MassachusettsBoston proposes the exploration of a new class of superconducting traveling wave parametric amplifier (TWPA) that exploits the large nonlinear inductance of a unique quantum device known as a superinductor. The nonlinear properties of the superinductor provide high gain of weak signals traveling in the forward direction, but exponential de-amplification of noise signals that may travel in the reverse direction through the amplifier. These attributes obviate the need for the specialized cryogenic microwave components like circulators and isolators that are required to isolate the Josephson parametric amplifiers used todaycomponents that normally consume significant space, produce unwanted magnetic fields, are costly, and degrade measurement performance. In addition, the proposed TWPA promises high dynamic range and wide bandwidth, making it robust, easily integrable into experimental setups, and cost-effective for researchers in the quantum information sciences or mixed signal domains. The proposed Phase I effort will study the required parameters, design the amplifier, and derive the expected performance of the TWPA device.

ABSTRACT: Size, weight, and power (SWaP) limitations restrict the ability of airborne radar systems to detect low-observable moving targets such as dismounts and slow vehicles in strong clutter. Solid State Scientific Corporation has developed a unique ground moving target indication signal processing algorithm which is ideal for SWaP limited systems due to its computational efficiency and its sensitivity to low-observable targets. During Phase I, data from a fielded radar system was processed with this innovative algorithm. The results of the analysis yielded improved performance and decreased computation time. During Phase II, the algorithm will be optimized and embedded in real-time processing on a fielded radar system. BENEFIT: The new radar processing mode will significantly reduce the false alarm rate for size, weight, and power limited systems performing moving target detection in mountainous and urban environments. This advance will improve the ability of unmanned aerial vehicles to perform intelligence, surveillance, and reconnaissance missions, thus enhancing the situational awareness for soldiers, intelligence officers, and commanders in order to identify threats and make critical decisions. The proliferation of unmanned aerial vehicle drone platforms is expected to continue since they offer a cost effective means for the U.S. DoD to conduct military operations despite reductions in troops on the ground.

ABSTRACT: Solid State Scientific Corporation (SSSC) is pleased to propose this SBIR program to design and develop a compact, long focal length, real-time, multi-spectral imaging sensor prototype for enhanced intelligence, reconnaissance and surveillance (ISR) from unmanned aerial vehicles (UAVs). The spectral bands in the proposed multi-spectral design are tuned to detect the anomalies from vehicle-borne improvised explosive devices (IEDs) during the day. At night, the spectral bands will support low-light level and active imaging. By leveraging the experience SSSC has garnered in micro-optics, the proposed multi-spectral sensor will have a long focal length but yet be as compact as a one color broad band sensor. The resulting spectral imager will simultaneously image four application-specific color bands in the Near Infrared-Short Wave Infrared (NIR-SWIR) band, and employ a 1280 x 1024 staring camera to capture one spectral data cube during each frame of the camera. The sensor will be equipped with the first ever real-time optical zoom capability over the range of 75-150mm. The sensor will be designed for integration into an existing payload on a Program of Record platform. BENEFIT: The new sensor will be compact which will result in decreased SWaP requirements compared to current systems. The multispectral system will include zoom capability which is advantageous for UAV ISR CONOPS. The specific application for the proposed imaging sensor is ISR including vehicle-borne IED detection, anomaly detection, low-light level and active imaging. Other potential applications for defense purposes include imaging through fog and smoke as well as situational awareness. In addition, we anticipate possible applications in law enforcement, homeland defense, and wildlife management.

ABSTRACT:During Phase I of the proposed effort, Solid State Scientific Corporation (SSSC) will develop the design for an innovative SAR/GMTI system to be deployed on hypersonic air vehicles traveling between Mach 5 and 7. Performing SAR and GMTI from a fast-moving hypersonic platform introduces a unique set of challenges on sensor array design, which are not present for typical airborne radar systems. In particular, advanced techniques are necessary to resolve the conflicting requirements of high resolution, large ground swath, compact array, low MDV, and hypersonic velocity. Technical objectives for Phase I include: (i) Develop an initial design by evaluating trade-offs between sensor geometry, radar operating parameters, CONOPs, and performance requirements, (ii) Identify and resolve radar system design challenges which are unique to hypersonic air vehicles, and (iii) validate the design using high-fidelity simulated data. The scope of the work will include a physics-based analysis, simulations, and literature review, to understand the effects of a hypersonic flow field on the ability to operate a radar on a hypersonic vehicle. Phase II work will include finalizing the design, and delivering to the Air Force a simulation tool to estimate SAR/GMTI performance for hypersonic vehicles and trajectories.BENEFIT:The anticipated benefits of this effort will include a significant advance in the understanding and design of radar systems for hypersonic air vehicles, thereby enhancing U.S. Air Force ISR capability.
