一种改进的机动目标“当前”统计模型的描述

An Improved Description of "Current" Statistical Model for Maneuvering Target

讨论了机动目标加速度的“当前”统计模型问题。推导出基于修正瑞利分布的机动目标加速度的“当前”统计模型的适用范围。提出一种改进的机动目标加速度的“当前”统计模型描述。仿真结果表明,基于本文提出的机动目标加速度“当前”统计模型建立的机动目标自适应跟踪算法,其跟踪精度更佳。

Some shortcomings of ＂current＂ statistical model for maneuvering target are discussed. The applicable bound of modified Rayleigh distribution was derived. Based on the result, a new ＂current＂ statistical model description was proposed. Computer simulation by MATLAB shows that the tracking accuracy of the new method is preferred to the old one.
