| Abstract: | 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... |
