| Abstract: | Interrupted-Sampling Repeater Jamming (ISRJ) is an advanced radar coherent interference based on the principle of under-sampling method, and achieves a train of false targets. In this paper, a joint transmitted waveform and mismatched filter design method focus on suppressing the ISRJ is proposed. Firstly, the mathematical optimization model is established by minimizing the transmitted signal pulse compression integrated sidelobe level and jamming signal mismatched filter output integrated level under the constraint of constant modulus waveform. Secondly, the analytical solution of transmitted waveform and mismatched filter is obtained by simplifing the optimization problem. By utilizing cyclic iterative algorithm, unimodular waveform and mismatched filter are produced. Finally, simulations are presented to assess the waveform and filter performance and anti-ISRJ performance. Simulation results demonstrated that the ISRJ is suppressed by jointly designing the waveform and filter. |
