摘要:

针对雷达线性调频信号和脉冲压缩处理,提出了一种新的调频灵巧噪声干扰技术.采用高斯白噪声对接收到的雷达信号的频率进行调制,得到干扰信号.通过控制高斯白噪声的带宽,可实现频域欺骗和多普勒频率窄带噪声干扰.该灵巧噪声与雷达信号具有较强的相关性,经匹配滤波后能获得较高的脉冲压缩处理增益,提高了干扰功率的利用率.

Abstract:

A new frequency modulation smart noise jamming technique is proposed against the radar linear frequency modulation(LFM) signal and pulse compression processing.The jamming signal is acquired by modulating the received radar signal frequency with gause white noise.It can produce frequency domain deceptive jamming and Doppler frequency narrowband noise jamming according to the gause white noise bandwidth.This smart noise jamming signal has much correlation with the radar signal, can get a high pulse compression gain after matched filtering and raising the jamming power efficiency.

Key words: electronic countermeasures, frequency modulation jamming, linear frequency modulation signals, pulse compression, frequency modulation smart noise, deceptive jamming
