摘　　要：针对Tong检测技术对高动态条件下的检测性能进行了分析。基于高动态大多普勒条件下的应用,进行了Tong检测技术改进研究,提出了改进后检测搜索策略,详细论述了策略改进依据。对搜索单元检测次数及检测概率进行了仿真,从仿真结果可以看出,对有信号搜索单元的驻留检测次数明显减少,总检测时间随之变小,有信号单元的总检测概率得到提高,满足高动态条件下的检测要求。The detection performance of Tong detector under high dynamic condition is analyzed in this paper firstly,then based on the application in high dynamic environment with large Doppler shift,an improved detection algorithm is propos ed,the improved detection and search strategy is put forward,and the basis for this improvement is described.Finally,the dwell number and detection probabil ity are simulated,and the simulation results prove that the improved method mee ts the demands of detection in high dynamic environment.
