一种新型机动目标跟踪算法——VDQ算法

目的 研究机动目标跟踪算法。方法 利用广义似然比技术对机动目标进行检测，既确保检测的可靠性，又满足系统实时性的要求。采用变维和估计系统状态相结合的方法，对机动目标进行跟踪，当目标机动较弱时，对系统状态用噪声方差进行估计，避免由于变维法带来的暂态误差。当目标机动较强时，则采用变维法。结果与结论 计算机仿真结果表明，这种新型机动目标跟踪算法具有良好的跟踪性能。

A New Algorithm of Maneuvering Target Tracking VDQ

Aim To study algorithms of maneuvering target tracking. Methods Generalized likelihood technology was used for reliability and real time to detect maneuvers. A new tracking algorithm was developed through combining the variable dimension with the state noise covariance estimation method. The state noise covariance estimation method was used to avoid transient error when maneuver is smaller. Results and Conclusion Computer simulation shows the algorithm has better tracking performance.
