Method for improving millimeter wave radar target speed ambiguity resolution multiple

The invention relates to a method for improving millimeter wave radar target speed ambiguity resolution multiples, which comprises the following steps: emitting more than three chirps in a wave emitting period, then calculating a plurality of single ambiguity multiples, then solving a multiple ambiguity multiple by utilizing the plurality of single ambiguity multiples, and finally calculating the real speed of a target based on the multiple ambiguity multiple. In the process of performing the target speed ambiguity resolution multiple, the maximum ambiguity multiple is the product of a plurality of single maximum ambiguity multiple, the maximum ambiguity multiple is greatly improved, and meanwhile, the error rate of speed ambiguity resolution is not increased. 本发明涉及一种提升毫米波雷达目标速度解模糊倍数的方法，其在一个发波周期发射三个以上啁啾，然后计算出多个单重模糊倍数，接着利用多个单重模糊倍数求取多重模糊倍数，最后基于该多重模糊倍数计算出目标的真实速度。本发明在进行目标速度解模糊倍数的过程中，最大模糊倍数为多个单重最大模糊倍数的乘积，大大提升了最大模糊倍数，同时又不增加速度解模糊的错误率。
