摘　　要：针对博弈对抗过程目标意图识别中的机动检测问题,设计了一种基于似然比检验的目标机动检测方法。该方法利用目标实时观测数据进行机动检测,将目标机动检测问题转化为目标观测时间序列数据检验问题。首先,基于极大似然原理对目标运动状态进行回归估计;其次,利用似然比检验原理设计检测模型,构建目标机动检测方法。仿真结果表明,该方法在噪声环境下具有较好的误检测和检测延迟性能。Aiming at the target maneuver detection in antagonistic process,a detection method is proposed based on likelihood ratio test.Based on the target real time observation data,the target detection problem is translated into the problem of time series data validation.Firstly,the maximum likelihood principle is applied to target regression state estimation.Then,the detection model is designed based on the principle of likelihood ratio detection,and the target maneuver detection method is constructed.Simulation result shows the improved misdetection and detection delay performance of the proposed method in the interference environment.
