The interrupted-sampling repeater jamming (ISRJ) is a mainstream jamming method in electronic warfare, simple yet implemented. With the rapid development of anti-ISRJ, due to the defects of ISRJ and the difficulty in ensuring real-time response, there is an urgent need to propose a new ISRJ-based jamming method based on simultaneous transmission and reception (STAR) technology. An interrupted-sampling multi-strategy forwarding jamming (ISMSFJ) with amplitude constraints is proposed by utilizing the characteristics of interrupted sampling in this paper. By modulating different interrupted sampling pulses on the intercepted signal and accurately controlling the delay time and weighting coefficient, it not only destroys the space distribution law of false targets, shortens the response time of the jammer, but also enhances the jamming amplitude or broadens the jamming range. For radar receivers, the jamming overlaps with the time-frequency information of the radar echo signal, and the time-frequency analysis anti-jamming algorithm fails. It can effectively resist the Fractional Fourier Transform anti-jamming algorithm for interpulse and intrapulse frequency-agile signals. The validity of the jamming technology is verified by theoretical analysis and simulation.

基于同时发送和接收技术的幅度约束间断采样多策略转发干扰

间断采样中继干扰（ISRJ）是电子战中的主流干扰方法，简单易行。随着反ISRJ的快速发展，由于ISRJ的缺陷以及难以保证实时响应，迫切需要提出一种基于同步传输和接收（STAR）技术的新型ISRJ干扰方法。该文利用中断采样的特点，提出了一种带幅度约束的中断采样多策略转发干扰（ISMSFJ）。通过对截获信号调制不同的断续采样脉冲，精确控制延迟时间和加权系数，不仅破坏了虚假目标的空间分布规律，缩短了干扰机的响应时间，而且增强了干扰幅度或展宽了干扰范围范围。对于雷达接收机来说，干扰与雷达回波信号的时频信息重叠，时频分析抗干扰算法失效。它可以有效抵抗脉冲间和脉冲内捷频信号的分数阶傅里叶变换抗干扰算法。通过理论分析和仿真验证了干扰技术的有效性。
