LFMCW毫米波雷达目标运动的补偿与鉴别

Motion Compensation and Moving Target Discrimination for LFMCW Millimeter - Wave Radar

本文针对宽带LFMCW毫米波雷达工作体制和制导应用背景,提出了一种用于高速运动平台对目标的运动进行补偿和鉴别的新方法。文中首先建立了运动目标在毫米波宽带线性调频连续波激励下的响应方程,然后给出了一维距离剖面像的运动补偿算法以及从运动杂波背景中鉴别运动与静止目标的方法,最后给出了计算机仿真结果,表明了本文方法的有效性。

In this paper,a novel method of motion compensation and moving target discrimina-tion is presented for LFMCW millimeter wave radar with guidance application. In the method, the response equation of moving target under wideband LFMCW stimulation is firstly established,then the algorithm of motion compensation of high resolution range profile and moving target discrimination under strong moving clutter background is given,and lastly the effectiveness of the method is shown by the results of computer simulation.
