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.
Abstract
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 frequen-cy 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.
