Robust Waveform and Filter Bank Design of Polarimetric Radar under Local Waveform Constraints

Joint design of transmit signal and receive filter bank for polarimetric radar with local waveform constraints is considered. Assuming Target Aspect Angle (TAA) unknown but belong to an interval, 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 transmit waveform in horizontal and vertical polarization channels, respectively, subject to energy and similarity constraints. An iterative optimization procedure that effectively solves the non-convex optimization problem is developed. The proposed method is validated through experimental results and compared with existing global design, thus showing its attractiveness.
