摘　　要：地面MPRF-PD雷达工作于中重频下,同时存在距离、速度模糊,雷达通常都会采用参差重频的工作方式进行解模糊,传统的解模糊方法本质为二进制积累,会带来信噪比损失,不利于小目标的检测。鉴于此,本文提出一种基于相参积累的地面MPRF-PD雷达二维联合解模糊算法,能够充分利用雷达脉冲资源,提高信噪比,可以同时有效实现小目标的检测与解模糊。Ground MPRF-PD radar works at middle pulse repetition frequency,leading to ambiguities of range and velocity.Staggered repetition frequency is usually used to resolve the ambiguities.The traditional method is essentially binary accumulation which results in signal-to-noise ratio loss and is not beneficial to small target detection.In view of this,a two-dimensional combined ambiguities resolution algorithm based on coherent accumulation for ground MPRF-PD radar was proposed in this paper.The proposed algorithm can make full use of radar pulse resources,to improve the signal-to-noise ratio and make it possible for the radar to detect the small targets and resolve their ambiguities effectively.
