The team of MMCOMM, Goleta Engineering (GE) and UCLA will develop techniques and technologies for the acquisition and exploitation of S-band micro-Doppler signatures applicable to navy S-band ballistic missile (BM) defense radars. We will build upon two directly applicable related prior efforts. The first is the ISAR ATR work we did for NRL to explore target signature data using time-frequency analysis algorithms. The second is the X-band micro-Doppler radar (MDR) we recently developed for NRL to collect micro-Doppler radar signatures. To this we will add specific UCLA expertise in radar signature prediction and feature extraction using advanced signal processing techniques. Our plan would be to provide an S-band MDR during phase I to acquire interesting signature data and then to process this data using our established time-frequency algorithms. One important part of collecting micro-Doppler signatures is target motion compensation during the potentially long target observation time to generate the potentially very fine Doppler resolution to extract the micro-Doppler signatures. For this we will use the signal based mocomp algorithms that GE developed on prior SBIR funding. We will explore potential target micro-Doppler phenomenology from analysis of candidate BM targets. We will investigate the potential application of the collection of micro-Doppler signatures to existing Naval S-band radar legacy assets
