摘要
提出了一种新的在线注入式相控阵雷达中频目标信号模拟方法,以线性调频信号为例,结合相控阵雷达目标回波的多通道接收特点,建立了和差信号的模型;然后研究了模拟产生的目标回波信号与雷达接收的原始回波信号的合成过程,给出了相应的合成方法,并且详细讨论了合成过程中的各种状态,对其中一些合成过程进行了仿真验证。研究为今后在线注入式相控阵雷达中频目标模拟器的研制提供了理论指导和设计借鉴。
The online injection IF target signal simulating method of phased array radar was put forward.The multichannel characteristics of the target returns of Phased Array Radar were analyzed,the models of sum and difference signal were given,then the synthesization of the target signal from the simulator and the original echo from radar was studied,and the corresponding method was provided.Every state in the synthesization process was discussed in detail,and the simulation verified this new method.Thus,a theoretical guidance and ideas for future develop for phased array radar online injection IF target simulator were provided.
