摘　　要：指显平台需接收各种测量设备按特定时间间隔发送的各类水下目标的位置信息,并实时、准确地显示目标航迹。与空中、陆上等目标相比,水下目标的测量周期长,测量信息常出现短暂中断,且由于传输网络的原因,指显平台接收的目标位置信息有时会出现乱序,现有的航迹异常值处理方法难以适用。通过对异常值处理方法进行了研究,给出了一种五点与九点线性预测法相结合的航迹异常值判定方法,同时给出了一种航迹自动修正方案,在出现多个航迹数据不稳定、因异常值处理导致的航迹偏离时能够自动恢复正确航迹,仿真结果验证了此方法的有效性。The platform for command and display needs to receive the position information of various underwater targets sent by various measuring equipment at specific time intervals,and display the target track in real time and accurately.Compared with air and land targets,the measurement period of underwater targets is long,and the measurement information is often interrupted for a short time.Due to the transmission network,the target position information received by the pointing platform is sometimes out of or⁃der,making the existing track outlier handling methods are difficult to apply.In this paper,a five-point and nine-point linear pre⁃diction method is presented to determine the track outliers,and an automatic track correction scheme is also given.The algorithm can automatically restore the correct track when multiple track data are unstable and track deviation caused by outlier processing.Simulation results verify the effectiveness of this method.
