摘要
噪声压制性干扰是当前火控雷达面临的主要有源干扰方式之一,进行干扰仿真对研究火控雷达干扰和抗干扰大有裨益。应用Matlab软件仿真平台,根据常见的噪声调制干扰信号的数学模型,以及火控雷达常用抗干扰信号处理模型,仿真噪声压制性干扰信号。分别仿真其通过MTI和脉冲压缩系统的干扰效果。对仿真结果进行分析,比较两种常见干扰信号的性能。结果表明:噪声调频信号是更适合用于火控雷达压制性干扰和雷达抗压制干扰能力评估的噪声调制干扰信号。
Noise suppressive jamming is the main active jamming style fire control radar faces. Doing jammming simulation is helpful for studying fire control radar＇s ECM and ECCM. According to the mathematic model of familiar noise-modulated jamming signal and ECCM signal processing model of fire control radar, the noise suppressive signal is simulated on the platform of Matlab. The jamming effect through MTI and pulse compression system is also separately simulated. Two familiar jamming signal are compared and it is shown that noise FM jamming signal is more suitable for suppressive jamming.
