脉间随机捷变频状态下运动目标回波特征分析

频率捷变、尤其是脉间随机捷变频是雷达重要的反电子对抗手段。但是当雷达工作于脉间随机捷变频状态时,一般只能进行非相参信号处理,这样大大降低了雷达的探测性能,尤其是对动目标的处理性能。研究雷达在捷变频状态时的相参处理方式具有重要的军事应用价值。以全相参、频率捷变、数字化信号处理等雷达体制为背景,构建并分析了雷达处于捷变频状态时运动目标数字视频回波信号的特征模型,可以为进一步研究、设计雷达捷变频相参处理方式提供理论依据。

Analysis of Echo Signal Characteristic of Moving Target in The State of Pulse-to-pulse Random Frequency Agility

The frequency agility,especially the pulse-to-pulse random frequency agility is the important anti-electronic countermeasure measure for the radar.However,the radar usually can proceed the incoherent signal processing only when the radar operates in the state of pulse-to-pulse random frequency agility,which will greatly reduce the detection performance of radar,especially the processing capability to the moving target.It is of very important military application value to research the coherent processing mod...
