The invention relates to a radar parking space detection method. A background noise signal of a radar is collected and processed; transmitting a signal through a radar, and obtaining an echo signal; calculating a signal weight and a target distance of the echo signal; the signal weight of the echo signal and the target distance are processed and compared with preset values, and the parking stall state is judged according to the comparison result. According to the technical scheme, the background noise signal is collected and obtained, the signal weight and the target distance value of the echo signal are calculated, and whether the vehicle exists in the parking space or not is judged through the two sets of numerical values and the preset threshold value. According to the detection method, the signal-to-noise ratio of the radar target signal can be improved, weak target signals are easier to distinguish, the problem that the radar cannot detect the car fuel tank is solved, and the problem of radar misjudgment is avoided.

    本发明涉及一种雷达车位检测方法,采集并处理雷达的背景噪声信号;通过雷达发射信号,并获取回波信号;计算回波信号的信号权重及目标距离;将回波信号的信号权重及目标距离处理,并与预设值进行比对,根据比对结果判断车位状态。本发明技术方案,通过先采集并获取背景噪声信号,并计算回波信号的信号权重、目标距离值,通过两组数值及预设阈值来判断车位内是否有车辆。该检测方法可以提高雷达目标信号的信噪比,更易于区分微弱的目标信号,解决雷达无法检测到小汽车油箱的问题,避免发生雷达误判的问题。
