雷达目标回波数据采集系统的设计与实现

The Design and Implementation of Data Acquisition System for Radar Target Returns

本文介绍了一种雷达目标回波高速自适应多通道数据采集系统的设计思想与系统结构。该系统采用双频采集方案，用固定的低采样率发现目标，用可变的高采样率详细记录目标回波。对雷达目标的检测与跟踪进行方位／距离双波门控制。该系统与主控微机配合可自动检测跟踪雷达天线扫描区域内的多个目标，高效地录取雷达目标回波。

This paper introduces the decign principle and the structure of a high-speed and adaptive multichannel radar data acquisition system. The system adopts a integrating scheme,name-ly,the combination of a low-speed sampling rate for target detection and a high-speed sampling rate for target data acquisition. The deteced target is tracked by a two-dimensional window which is composed of an azimuth gate and a range gate.Working with a microcomputer,the recording system can automatically detect and track multiple radar targets in the total radar scanning area,and ac-quire the returns of interested targets efficiently.
