Radar installation angle calibration method

The invention relates to a calibration method for a radar installation angle, and the method enables the radar transmission frequency to be designed to be in a 0 sweep frequency mode, thereby achieving the anti-interference effect on an environment obstacle because the environment obstacle cannot be detected by the radar in the 0 sweep frequency mode. And then a signal of which the frequency difference with the radar is within a radar detection range is transmitted through a subject matter, and an intermediate frequency signal equivalent to a fixed distance speed is simulated, so that the same effect as that of a Doppler analog signal transmitter is achieved without complex hardware design, and the cost can be reduced. 本发明涉及一种雷达安装角度的标定方法，其将雷达发射频率设计为0扫频模式，从而实现了对环境障碍物的抗干扰作用，因为环境障碍物在0扫频模式下无法被雷达检测到。然后通过标的物发射出与雷达频率差在雷达检测范围内的信号，模拟一个等效于距离速度固定的中频信号，达到与多普勒模拟信号发射器一样的效果而不需要那么复杂的硬件设计，所以能够减少成本。
