在泊车中通常有多个障碍物或外形特殊的障碍物，而采用传统倒车雷达的单发单收直线计算方法时测距误差很大，且不能确定障碍物方位。本文针对该问题提出一种单发多收联合三角函数算法的测距方法，通过此方法得到障碍物到车尾的垂直距离，明显提高了探测精准度。同时提出建立点坐标矩阵数据库、通过查表方式快速定位，大大减少运算量，提高雷达响应灵敏度。同时可以确定障碍物的水平方位，实现障碍物虚拟可视化。
在泊車中通常有多箇障礙物或外形特殊的障礙物，而採用傳統倒車雷達的單髮單收直線計算方法時測距誤差很大，且不能確定障礙物方位。本文針對該問題提齣一種單髮多收聯閤三角函數算法的測距方法，通過此方法得到障礙物到車尾的垂直距離，明顯提高瞭探測精準度。同時提齣建立點坐標矩陣數據庫、通過查錶方式快速定位，大大減少運算量，提高雷達響應靈敏度。同時可以確定障礙物的水平方位，實現障礙物虛擬可視化。

Multiple obstacles or special shape obstacles exists in the parking, while the traditional single shot single receive linear distance calculation method is inaccurate and can not probe the position. This paper presents a distance measurement method that combine single shot multiple receive with trigonometric to get the target distance. And it improves the detection accuracy obviously. Besides, the paper proposed the establishment of a dot matrix database, which can quickly locate by querying forms, and reduce the calculation to enhance response sensitivity. Also it can probe horizontal orientation of the obstacle, and to realize virtual visual obstructions.
