The proposed digital radar transceiver will support a range of NASA missions, including synthetic aperture radar (SAR) imaging, moving object detection and tracking in surface and volume search applications, object and surface characterization and identification, remote sensing, sounding, and navigation. Trident's Reconfigurable Adaptive Programmable Tactical Open Radar (RAPTOR) architecture is extremely scalable, configurable, and programmable, enabling support for a wide range of radar modes, on a pulse-to-pulse, or CPI-to-CPI (coherent processing interval) basis, as well as flexibility in system topology, supporting bistatic-multistatic and MIMO configurations. Trident's staff has extensive background in supporting NASA missions and our strategy for this project is to design and develop a long-term, miniaturized common building block, fully reprogrammable on-board processor board suitable for potential technology insertion into NASA's planned Earth science missions including DESDynI, GRACE FO, SWOT, and PACE, as well as supporting pre-formulation studies for the OCO-3 instrument, CLARREO, ASCENDS, ACE, GEO-CAPE, HypIRI, as well as the Venture class science technology demonstration projects. The results of this project will also support technology insertion in NASA Planetary science missions currently under formulation including the New Frontiers OSIRIS-Rex. The proposed digital radar transceiver has significant application for defense and other government applications, where its small size, weight, and power footprint make it applicable to rapid-response small satellite missions for intelligence collection and remote sensing. Its FPGA-based digital programmability also offers flexibility for implementation of capabilities beyond simple radar, including software defined radio, on a common set of hardware.
