针对传统的天波雷达海杂波循环对消法无法自适应判断对消次数的问题,研究了一种改进的方法即基于参考相邻单元的海杂波循环对消法.该方法用当前海面检测分辨单元所在的子区内其他分辨单元的回波信号构建参考信号,并利用从参考信号提取出的海杂波多普勒频率参数对检测单元进行海杂波循环对消.通过理论分析和实测数据验证,证明了该方法的有效性.
Aiming at the problem that the traditional sky wave radar sea clutter cancellation method can not adaptively determine the number of cancellation times, an improved method based on reference adjacent cells is proposed. This method uses the current sea surface detection The reference signal is constructed based on the echo signals of other resolving units in the subarea where the unit is located and the sea clutter cyclic cancellation is performed on the detecting unit by using the sea clutter Doppler frequency parameter extracted from the reference signal.According to theoretical analysis and measured data Verification proved the validity of this method.
