摘　　要：目前毫米波雷达导引头常采用频率步进信号实现高分辨一维距离像,该信号具有合成带宽大、波形设计灵活和抗干扰能力强等特点,因此针对频率步进雷达的回波模拟和干扰研究具有重要意义。本文以自卫干扰为对抗场景,考虑实际对抗中干扰系统的滞后性,分析和仿真了常规噪声压制和存储转发的干扰效果,可为干扰设备的设计和使用提供一定参考。At present,millimeter-wave radar seekers often use stepped frequency signals to obtain high-resolution range profile.The stepped frequency signals feature large synthetic bandwidth,flexible waveform design,and strong anti-jamming capabilities.Therefore,it is of great significance to simulate the echoes of the stepped frequency radar and to study matching jamming techniques.This paper analyzes and simulates the jamming effect of the conventional noise suppression and storage forward jamming techniques in self-defense countermeasures scenarios,with the hysteresis of the jamming systems in actual countermeasures being taken into consideration.It can provide some reference for the design and use of related jamming equipment.
