摘　　要：为了解决多项式相位法检测机动目标时存在计算复杂度过高、伪谱峰干扰严重、系统检测效率过低等问题,提出了改进的算法。在此基础上给出了基于改进算法的距离-加速度谱图检测目标机动信息的模式并证明了该检测模式的合理性。利用实测数据进行了仿真,仿真结果验证了该改进算法在高频雷达机动目标检测方面的有效性。To solve the existing problems with the algorithm of polynomial phase on maneuvering target detection, such as high computation complexity, serious pseudo spectrum peak interference and low detection efficiency of the system, an improved, algorithm is given in this paper. Based on that, a new mode of detection of information about maneuvering target on the basis of range-acceleration spectrum of the improved algorithm is proposed and its rationality is testified. Simulation based on real data is done and the result validates the efficiency of the improved algorithm on maneuvering target detection for high-frequency radar.
