摘要
利用带加速度补偿的频谱分析方法识别调频连续波雷达(CWFM)受到的速度拖引干扰.通过对雷达回波进行若干次预置的线性调频补偿,对其频谱图进行二维识别,并估计出速度拖引干扰的拖引参数,从而使CWFM雷达及时摆脱干扰并恢复到正常的速度跟踪状态.
The realization technique for recognition of the velocity deception jamming in CWFM radar system is discussed in this paper. This method is based on spectrum analysis with frequency compensations. The radar echoes are weighted with a series of preset nonlinear phased functions. Its spectrums are analyzed in 2-dimensional manner and the deception parameter is estimated . It makes the CWFM radar free itself from being affected and restore to its normal velocity tracking procedure when the interference disappeared.
