雷达侦察系统复杂电磁环境适应性分析

Radar reconnaissance system's suitability for complex electromagnetic environment

雷达侦察系统面临的复杂电磁环境包括密集的雷达信号,非雷达信号以及噪声和干扰。分析了雷达侦察系统适应复杂电磁环境能力,提出了对非雷达信号及噪声和干扰进行抑制,对雷达信号进行有效侦收的措施和方法。最后用门限变化进行抗干扰检测,说明雷达侦察系统可以有条件适应复杂电磁环境。

The complex electromagnetic environment,which the modern electronic intercept systems must face to,means the density of diverse radar signals,non-radar signals,noise and jamming.The ability of a radar reconnaissance system suitable for the complex electromagnetic environment is analyzed,and the effective measurements of radar signal interception and processing are proposed while the non-radar signals,noise or jamming are suppressed efficiently.An example is illustrated that radar reconnaissance systems can adapt to complex electromagnetic environment more or less under necessary conditions.
