As a new type of coherent jamming pattern in modern electronic warfare, Interrupted Sampling Repeater Jamming (ISRJ) has attracted increasing attention in past decades. In this paper, the joint optimization of transmit waveform and receive filter for wideband polarimetric radars is introduced to increase the freedom degrees of radar anti-ISRJ design. The figure of merit is formulated on the basis of the penalty function and Pareto balance framework. Different from off-the-shelf anti-jamming methods employing waveform design, the modulation of Target Impulse Response Matrix (TIRM) to the target echo is considered in the system model, for the sake of matching with a wideband illumination scenario. To solve the non-convex problem, a Majorization-Minimization (MM) based alternate iteration method is proposed. Numerical results validate the effectiveness of the proposed method, and highlight that compared to conventional single-polarization radars, a better anti-ISRJ performance can be achieved by waveform design of polarimetric radars.
