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, aiming at the background of wideband LFMCW millimeter-wave radar working system and guidance application, a new method is proposed for high-speed motion platform to compensate and discriminate the target’s motion. Firstly, the response equation of the moving target under the millimeter-wave wideband chirped continuous-wave excitation is established. Then, the motion compensation algorithm of the one-dimensional distance section image and the method of identifying the moving and stationary targets from the moving clutter background are given. Finally, The computer simulation results show the effectiveness of the proposed method.
