针对宽带高分辨雷达体制下的未知速度运动目标检测问题, 基于高分辨一维距离像提出一种新的非相干积累算法. 首先利用改进的双向维特比算法估计目标速度及强散射点位置, 提高了低信噪比下

的估计精度, 然后在强散射点周围选取待检测单元进行非相干积累, 进一步提升了检测性能. 两类飞机实测数据的多个实验结果表明, 当目标发生距离走动的情况下, 该算法性能相对传统的非相干积累算法有明显的提高.-For unknown broadband speed moving target detection problem under high resolution radar system, based on high resolution range profile propose a new non-coherent integration algorithm. Firstly, improved bidirectional Viterbi algorithm to estimate the target speed and strong scattering point, raise the estimation accuracy of multiple experiments under low SNR, then select points around the strong scattering detection unit to be non-coherent integration, to further enhance the detection performance. measured data show two types of aircraft, when the target occurrence walking distance Next, the algorithm performance compared to traditional non-coherent integration algorithm has been significantly improve
