The US Army is seeking a high-resolution, rail-based synthetic aperture radar (SAR) imaging system capable of operating within the 100300GHz frequency range. Wide bandwidth SAR technologies at this frequency range provide the potential for supporting applications that require high-resolution, non-destructive imaging. In response to this opportunity, MaXentric is proposing a rail-based SAR system codenamed M-CRISP (Multi-Channel Rail-based Radar Imaging Sensor Platform). The proposed architecture moves a set of radar transceivers over a large effective aperture to increase the achievable resolution. Advanced multi-band super-resolution techniques are applied to the radar measurements to produce high-resolution images for scatterer detection and classification. During the Phase I effort, our team designed a multi-band sensor architecture and simulated candidate super-resolution SAR algorithms. A dual-band mmW SAR system was constructed and used to demonstrate algorithm performance. During the proposed Phase II effort, modular prototype SAR platforms will be constructed to allow testing and demonstration a several mmW and EHF bands of interest. These measurement platforms will be used refine candidate imaging, detection, and classification algorithms. During Phase II, the M-CRISP system will be tested for several potential Phase III applications to assess its performance and provide insight on design changes for future SAR imaging
