中文摘要:受波束调度灵活性、接收通道数目限制,目前分集相控毫米波防撞雷达主要采用距离/方位二维扫描.由于缺乏目标高度信息,若雷达前方出现不影响载体通行的高/低目标,容易造成防撞雷达的障碍误报.针对这一问题,本文提出基于MIMO和分集相控雷达结合的天线排布和信号处理方法,实现对场景的三维检测.与二维防撞雷达相比,该方法在不增加雷达接收通道数且几乎不增加雷达尺寸的前提下能有效实现方位和俯仰的联合测角.与二维稀布接收阵雷达相比,本文设计雷达不会产生方位栅瓣,适合复杂背景下的多目标检测.

Design of three-dimensional millimeter wave radar for collision avoidance
Abstract:Limited by the flexibility of beam scheduling and receiving channel number, the range/azimuth two-dimensional (2D) scan is mainly used in the current diversity phased array radar for collision avoidance. Due to the lack of targets" height information, if there is a high/low target in front of the radar which does not affect the passage of the carrier, it will likely to cause false alarm. Aiming at this problem, this paper proposes an antenna layout and signal processing method based on the combination of MIMO and diversity phased array radar to realize the three-dimensional detection. Compared with the two-dimensional collision avoidance radar, this method can effectively realize 3D detection without increasing the number of radar receiving channels and the radar size. Compared with the 2D sparse array radar, the radar designed in this paper does not generate azimuth grating lobe, which is suitable for multi-target detection under complex background.
