分析了多目标跟踪过程中预测误差的来源、分布及传递关系,计算出目标的测量误差和本机的速度测量误差在坐标转换后的偏差,并根据目标的机动特性建立了相应的机动加速度模型.讨论了如何在保证正确判定概率PCD条件下选取尽可能小的跟踪门体积,给出了跟踪门的设计,并说明了系统扫描方式对跟踪门设计的影响.还建立了目标的状态方程和测量方程,运用标准Kalman滤波,实现了机载IRST系统的多目标跟踪,并对仿真结果进行了分析.

The sources of the prediction error were analyzed; and the distribution and the propagation of the error were considered. The measurement error of the target and the velocity error of the ownship were calculated. The error caused by target maneuvering was considered. Then how to obtain the tracking gate of the minimunm volumn was discussed. The relation between the scanning method of the system and the tracking gate was also analyzed. After the state equation and measurement eqution were formed, a conventional Kalman filter was used for multi-target tracking. And the result illustrates that the design of tracking gate is better than before.
