摘要
雷达干扰系统中的干扰信号设计与性能分析是一个难点。噪声调幅信号是雷达干扰系统中常用的一种信号,以噪声调幅干扰为例,通过分析噪声调幅干扰的原理,建立了一个简单的噪声调幅信号模型,利用Simulink语言对噪声调幅干扰进行建模仿真,针对频率对准、频率瞄准误差为半个中放带宽和频率瞄准误差大于半个中放带宽三种情况得到在不同条件下噪声调幅信号对雷达系统的干扰效果,结果显示在瞄准式干扰的条件下噪声调幅信号对雷达信号的干扰效果最为显著,说明噪声调幅信号适用于瞄准式干扰。
Design and performance analysis of jamming signal are difficult in radar jamming system, noise amplitude modulation jamming is a common used signal in the system. Taking an example of noise amplitude modulation jamming, with analyzing the principle of noise amplitude modulation, the model of noise amplitude modulation is built by simulink language. Alignment for frequency, frequency targeting error of the half- bandwidth and frequency of targeting error in more than half the bandwidth of three conditions be put under different conditions noise in the AM signal on the radar systems of interference effects. The jamming resultion is obtained in different conditions. Simulation results is satisfactory in the spot jamming condition.
