摘要
用普通录像机和专用接口电路,组成雷达信号记录设备,对箔条干扰的雷达回波视频信号以及雷达接收机中如自动增益控制电压等低频信号进行了成功的记录,并将这些录取的信号送微型计算机进行分析处理.处理结果表明,箔条回波在时域宽度、周期性、幅度概率分布、频谱形状等多种特征上与目标回波信号、噪声干扰信号、同频异步调制干扰信号等有明显的区别,从而可以实现箔条干扰存在与否的在线实时判定。
ChafTecho and target echo signals are recorded by a radar signal recording equipment which is composed of a video recorder and special interfaces, and then all of them are sent to the microcomputer for analysing and identifying. The results indicate that the chaff echo signal is evidently different from the target echo signal, noise jamming signal and some modulated jamming signal in time domain width, periodicity, amplitude probability distribution, frequency spectrum form, etc. So the automatic identification of chaff jamming could be implemented on -line and in real time.
