摘　　要：短波电台对天波超视距雷达有时会构成严重的干扰 ,为此提出将随机二相码连续波雷达技术用于该雷达 ,以提高其抗干扰性能。本文分析了线性调频和相位编码体制天波超视距雷达对抗短波干扰的性能 ,并进行了计算机仿真。结果表明随机二相码天波超视距雷达比线性调频天波超视距雷达可具有更强的抗短波干扰能力。The over the horizon radar (OTHR) can sometimes be interfered seriously by the shortwave radio station. So the random binary phase coded (RBPC) CW radar was presented to be used in OTHR for the property improvement of anti jamming. The characteristics of the RBPC CW radar and the LFM CW radar in case of the shortwave radio station jamming were analyzed. The computer simulation shows that the RBPC CW radar has better property of suppression of shortwave jamming than the LFM CW radar.
