| 摘 要： | 岸-舰双基地波超视距雷达采用岸基阵列发射、舰载单根全向天线接收，且各发射阵元所用载频不同。本文首先分析了该雷达直达波特性，分析表明直达波可看成来自特定距离、特定方位的干扰，具有特定的多普勒频率，据此提出时域、距离-方位域以及多普勒域直达波抑制方法。从运算量、处理增益、输出信干噪比等方面对三种方法的性能进行了分析，计算机仿真以及实测数据结果表明直达波抑制方法的有效性。

| Abstract: | Bistatic Surface-Wave Over-the-Horizon Radar(SWOTHR)uses a coast-located array to transmit signals and a ship-carried omnidirectional antenna to receive echoes.In the transmit array,different element utilizes different carrier frequency.The analysis of the direct-path-interference leads to the conclusion that the direct wave is a kind of interference at a position and with a Doppler frequency.Based on the conclusion the interference suppression in time,range-angle and Doppler domain respectively is presente... |
