Abstract

We focus on the robust joint design of the transmit waveform and filtering structure for Polarimetrie radar. Assuming signal-dependent interference and Target Aspect Angle (TAA), we consider the worst-case Signal to Interference plus Noise Ratio (SINR) at the output of the filter bank as the figure of merit to optimize under both a similarity and an energy constraint on the transmit signal. We develop an iterative optimization procedure that monotonically improves the worst-case SINR and converges to a stationary point. The proposed method is validated through experimental results and compared with existing “TAA-aware” alternatives, thus showing its attractiveness.
