摘　　要：多径效应是影响和限制单脉冲二次雷达探测性能的最主要因素。为了削弱多径效应对二次雷达测角精度的影响,提出了OBA曲面函数结合累加权重的处理方法。通过理论分析及对实际接收信号进行处理,结果表明该方法能有效地降低干扰并且明显提高测角精度。The multipath effect is the most important factor that can affect and limit the detection performance of the monopulse secondary surveillance radar. In order to reduce the influence of the multipath effect on the angle measurement accuracy of the secondary surveillance radar,the OBA surface function is proposed combined with the accumulative weight method. Through the theoretical analysis and the processing of the signals received,the results indicate that the method can effectively reduce the interference and improve the angle measurement accuracy.
