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

"This topic is concerned with the development of a concept for an advanced MMW SAR/MTI sensor for UAV applications that will support future battlefield requirements that are beyond those currently available. This advanced sensor includes an antenna,transmitter, receiver, and signal preprocessor. Radar techniques that are to be considered will be compatible with various operational modes of a Synthetic Aperture Radar (SAR) system and a Moving Target Indicator (MTI) system. Challenges that are to beaddressed in this concept definition are:1) Determining the most productive and cost effective way to produce the transmit power required for the sensor to meet the ten (10) kilometer range capability.2) Formulating signal preprocessing techniques that will provide increased gains to the system to minimize the peak and average transmit power requirements.3) Packaging the sensor in the volume constraints that will meet the power and thermal requirements.4) Development of an antenna that will meet the requirements defined by the sensors specifications and the packaging constraints imposed by the available "real estate" on the UAV.5) Integrating both a SAR mode and a MTI mode into a single sensor. The development of this product will lead to the development of a compact sensor that may be used for military and commercial applications. Other uses for the sensor would include terrain mapping for changes in enviromental conditions, medical imag
