中文说明：对20路通道的雷达数据进行从新排布，保证每一个有效目标的起始过程都在一个通道内，以便于后续对雷达探测性能进行分析。雷达采集的数据格式需要满足正好60列，每个目标安相对速度，方位角，距离顺序排列。
English Description：
The radar data of 20 channels are rearranged to ensure that the starting process of each effective target is in one channel, so as to facilitate the subsequent analysis of radar detection performance. The data format of radar acquisition needs to meet exactly 60 columns, and each target is arranged in the order of relative velocity, azimuth and distance.
