一种雷达目标俯仰角判定方法

A Target Elevation Angle Determination Method

毫米波雷达在ADAS系统中广泛应用,针对ADAS系统车载雷达需要实现俯仰检测这一需求,本文在不明显增加运算量的前提下,提出了一种新的基于天线俯仰宽窄波设计的俯仰判定方法。该方法原理简单,实现方便,在不影响方位测角的情况下使雷达具备俯仰判定能力。暗室数据和道路测试数据验证了算法的有效性。

Millimeter wave radar is widely used in ADAS system.In view of the practical need to achieve elevation angle detection for the automotive radar in ADAS system,a new elevation angle determination method based on the design of wide and narrow elevation antenna beams is put forward in this paper.The method is simple in principle,convenient to realize,and makes the radar have the ability of elevation judgment without affecting the azimuth angle measurement.The effectiveness of the algorithm is verified by the data measured from the microwave anechoic chamber and road test.
