双基地多输入多输出雷达距离欺骗干扰识别技术

Recognition technique of range deception jamming for bistatic MIMO radar

针对双基地多输入多输出(Multiple Input Multiple Output,MIMO)雷达面临的距离欺骗干扰问题,提出了一种基于角度定位的距离欺骗干扰识别方法.该方法利用双基地MIMO雷达能够同时测量目标相对于收发阵列的角度、存在信息盈余这一特点,将通过收发角度估算得到的目标距离和与实测距离和相减并与理论的测量极限误差进行比对,最终实现对距离欺骗干扰与真实目标信号的判定识别.理论分析以及仿真结果验证了所提方法的有效性和可行性.

A recognition method of range deception jamming based on augury localization is proposed to solve the range deception jamming problem of bistatic MIMO radar.Bistatic MIMO radar can simultaneously measure the direction of departure(DOD)and direction of arrival(DOA)of the target which means an information surplus.By the way of comparing the limiting error with the difference between the range sum of target calculated using transceiver angles and the range sum measured directly,the recognition for distance deception jamming or the target echo the method can be ultimately realized.Theoretical analysis and simulation results show the effectiveness and feasibility of the proposed method.
