Space-Qualifiable Digital Radar Transceiver

Radar technology offers a very flexible, powerful tool for applications such as object detection, tracking, and characterization, as well as remote sensing, imaging, sounding, weather measurement and analysis. Historically, radar systems have tended to be either large, complex, power-hungry, purpose-built systems, or extremely simple systems of limited capability. More recently, miniaturization of high-performance programmable integrated circuit technologies as embodied in field-programmable gate arrays, as well as rapid advances in high-speed data conversion technologies at a gigasample per second and beyond, have enabled the implementation of direct-conversion radio frequency (RF) systems, including radar, that operate almost completely in the digital domain. In addition, solid-state high-power RF device technologies have improved in efficiency and speed to the point where highly efficient pulsed transmit sources are possible. As these device technologies have matured, their application in space environments has accelerated to the point where extremely flexible programmable radar systems can be implemented in a very small size, weight, and power footprint. Trident Systems has developed a powerful radar architecture called RAPTOR, validating it through flight testing on a number of Department of Defense programs; initial analysis has shown the feasibility of transitioning this design to the space environment. Through a comprehensive program of requirements development, trade studies, critical component and design analyses, fault mitigation simulation, and system design, Trident will develop the design for a complete space-qualifiable UHF/L-band radar transceiver in a 96mm x 90mm x 31mm PC-104e form factor that meets all customer mission needs, and is applicable to a wide range of applications (NASA and others). By basing the solution on Trident's proven RAPTOR technology, the system will rapidly achieve a high TRL.
