摘要
介绍了基于DDS技术实现系统幅相控制的 8单元收发全DBF(数字波束形成 )相控阵雷达的基本原理 ,并讨论了天线、全数字T/R组件、系统软件等各分系统组成。同时介绍了该雷达系统的工作过程、系统校正过程 ,还给出了实际测量的系统各发射通道的幅相误差、误差补偿后不同加权的发射方向图。
Basic principles of 8 element DBF phased array radar, whose amplitude and phase control is based on DDS technology, are introduced in this paper. Each subsystem such as antenna, digital T/R module, system software is discussed. The operation process and calibration process of the radar system are also covered. In same time, the measured amplitude and phase errors of transmitting channels, transmitting patterns, transmitting nulling patterns and receiving pattern after error calibration are provided.
