摘要
针对对空警戒雷达整机测试中,动态目标模拟难的问题,本文设计开发了一个高性能信号源——雷达在线测试仪。文中采用可编程逻辑器件,用拨码开关调节产生复杂的组合逻辑时序,控制雷达波形产生器和频率合成器,模拟空中真实目标,产生多种高频目标回波信号。在雷达不开发射机的情况下,实现对雷达视频模式、点迹模式、录取方式、波形选择、量程控制、视频挖除、警戒设置等整机功能的检查及雷达录取精度参数的测试。对工程应用具有很大的实用价值和指导意义。
Based on the issue of the dynamic target simulation on warning radar test, this text designed and developed a high-performance signal sources-Radar Online Tester. The tester adopts the complex programmable logic device （CPLD） ,and uses the dial code switching to generate complex Combinatory logic succession, which can control radar waveform producer and the frequency synthesizer to simulate actual target on air for generating many kinds of high frequency target echo signal. In the situation that the radar transmitter is not opened, the tester can realize the radar video pattern, the point track pattern, the enrollment way, the waveforrn choice, the measuring range control, the video eliminating, guard setting and so on , for complete function inspection and radar enrollment precision parameter testing. The study has very great practical value and directive significance for the proiect annlicatinn
