Optimizing polarimetrie radar waveform and filter bank for extended targets in clutter

What is it about?

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.
