摘　　要：高频超视距雷达是目前世界上研究很多的一种雷达,具有探测距离远,抗干扰能力强,抗隐身等特点,通常采用大时宽带宽信号。脉冲压缩是现代雷达普遍采用的一种信号处理方式。通过探讨运用多通道频域脉压技术解决大时宽相位编码信号的雷达系统由于脉冲压缩处理而造成运动目标检测性能下降的问题,在分析频域脉压原理和旁瓣抑制原理的基础上给出了多通道频域脉压实现框图。Now people put a new premium on high-frequency over-the-horizon radar s research because of its many advantages in detection range,anti-jamming and anti-stealth.High-frequency over-the-horizon Radar usually adopts a wide time-bandwidth signal.A method of signal process that modern radars adopt generally is the pulse compression.It is discussed emphatically in the article that how to make use of multichannel frequency domain to resolve a problem.The problem is that measuring performance of moving target will...
