Abstract

As the need for radar applications has become more urgent, conventional radar performance does not meet the current demand for observation. In recent years, the MIMO radar is considered to have great potential. MIMO SAR can get more phase center for imaging, interference, GMTI, or any other application. Waveform design is the key point of MIMO SAR, and it's also the current biggest bottlenecks of MIMO SAR implementation. We prove that the DFCW/OFDM signal can hardly meet the required performance for MIMO SAR while the experiments focus on extended targets imaging.
