MARK Resources proposes to design and eventually develop a small SAR system for use in diagnostic imaging of a variety of targets and low-observable materials at relatively short range. The SAR system will be designed to operate in the 6-18 GHz and 33-37 GHz frequency bands. The modulation bandwidth will be 4 GHz, which will provide a range resolution cell of 5 cm. Full polarization capability is included in the design, as well as bistatic and multistatic operation.One concept is a true handheld device, weighing just a few pounds, where the synthetic aperture is created by physically moving the radar along a path. Success of this concept depends on knowing the precise location of the radar versus time so that the radar data can be focused to a point of interest on the test object. An inertial sensor will be employed for this measurement, which will be based on modern micro-electro-mechanical system (MEMS) technology. The other concept is an antenna array that is small enough to be considered portable. The range of the array antenna configuration will be limited due to the constrained length of the antenna that is considered portable.high resolution radar,multi-object tracker,bird tracker,radar signal processing
