| 摘 要： | 介绍了一种VHF有源相控阵雷达收发组件中的数字收发单元。采用分布式高速D/A和A/D分别实现为每个天线单元产生独立射频发射信号和采集每个天线单元接收的回波,使每个单元发射的波形和采集到的回波信号能单独处理。所有数字单元通过嵌入式以太网接口连接到主控计算机。该数字单元在雷达信号处理方面具有灵活性强\,高性能、可扩展和低成本的特点。

| Abstract: | A digital transceiver unit of VHF active phased array radar’s T/R module was introduced.Distributed high speed D/A and A/D were invoked to generate RF transmission signal for every antenna high speed,and to sample echo signal of every antenna,thus both transmission waveform and echo signal of antenna units could be processed independently.All digital units were connected to center control computer with embedded Ethernet.This digital unit design has great flexibility in radar signal processing,and it is high performance,high scalability and low cost. |
