摘要: 本发明涉及一种毫米波防撞雷达目标探测方法,包括以下步骤:毫米波防撞雷达根据其发射波形的不同,分别采集相应波形所对应的回波数据;对各种波形的回波数据进行频域变换,得到回波的频谱;对各种波形的回波频谱进行频域压扩处理,补偿距离引起的不同频率分量的衰减,抑制低频干扰分量,得到有效的回波频谱;对上述回波频谱进行目标初次检测处理;对初次检测结果进行频率相关和过滤处理,而到二次检测结果;利用二次检测结果估计雷达探测目标的位置和速度。本发明能够有效的实现毫米波防撞雷达的目标探测,提高毫米波防撞雷达在复杂环境下的实用性。
英文摘要: The invention relates to a target detection method for a millimeter-wave anticollision radar. The target detection method comprises the following steps of: respectively acquiring echo data corresponding to relevant waveforms by the millimeter-wave anticollision radar according to different waveforms emitted by the millimeter-wave anticollision radar performing frequency domain transformation on the echo data of the various waveforms to obtain an echo frequency spectrum performing frequency domain companding processing on the echo frequency spectrums of the various waveforms, compensating the attenuation of different frequency components caused by distances, restraining low-frequency interference components and thus obtaining an effective echo frequency spectrum performing preliminary target detection processing on the echo frequency spectrum performing frequency association and filtering processing on a preliminary detection result and thus obtaining a secondary detection result and estimating the position and the speed of a target detected by the radar. According to the target detection method, target detection by the millimeter-wave anticollision radar can be realized effectively, and the practicability of the millimeter-wave anticollision radar under a complex environment is improved.
