Lightweight mm-Wave Synthetic Aperture Radar/Moving Target Indicator (SAR/MTI) Sensor for Small Unit UAV

"Goleta Engineering (GE) and MMCOMM with support from Northrop-Grumman will design and develop a lightweight MMW SAR/MTI system in the 10 to 20 pound range for installation on a small UAV to support small unit operations. Many key enabling technologiesneed to be matured to facilitate the timely development and fielding of a lightweight SAR/MTI system. We will leverage off of existing and emerging technologies such as a 7 pound dual-mode seeker to evolve thru extensive tradeoffs a family of alternatedesigns in the 10 to 20 pound range. One of these designs will then be down selected for further development in the Option phase and demonstration in Phase II. The baseline design employs an FMCW waveform, MMIC hardware including a GAAS FET poweramplifier and efficient signal processing. One of the key enabling technologies for implementing the liteweight SAR is signal based motion compensation (SBMC) to reduce the dependence on a motion measurement sensor (MMS). This capability has beendeveloped and demonstrated on prior efforts by GE. MMCOMM, a MMW hardware company, provides the capability to develop and produce the lightweight MMW MMIC componentry. Northrop-Grumman provides expertise in UAV SAR applications and a path to Phase IIICommercialization. The U S Army will mature lightweight MMW SAR/MTI technology and develop a system for installation on a small UAV that can be used to support small unit operations. In Phase I, the US
