Abstract： Shift frequency interrupted sampling repeat jamming （SFISRJ） combines the advantages of both types of interference and poses a serious threat to radar detection.An anti-SFISRJ method based on waveform and mismatch filter design is proposed. Taking both interference suppression and pulse compression performance into account，an unconstrained multi-objective joint optimization model is established，the gradient of the objective function is derived，and a joint design method based on limited-memory Broyden Fletcher Goldfarb and Shannon （L-BFGS） is proposed.The feasibility of the proposed algorithm is verified simulation， especially when the real and fake targets are inseparable in the time and time-frequency domains，the proposed algorithm can achieve the best anti-interference performance compared to traditional methods.

Keywords： shift-frequency interrupted sampling repeater jamming （SFISRJ）；waveform design；mismatchec filter；gradient descent
