多方位-速度目标跟踪法性能分析

对潜艇水下跟踪目标的一种方法-多方位-速度法进行了深入分析,发现它具有独特的性能.首先分析了系统的观测性,得出了系统可观测的两个必要条件.之后对两种可能的建模思路进行了分析,指出了一种常见的建模错误,它使得已知的目标速度未能得到利用,效果等同于仅方位法.最后对目标航向的多解现象进行了分析,指出多解性是多方位一速度法的一个基本性质.结合有关性能,还将多方位-速度跟踪和仅方位跟踪进行了比较.

Properties of a Method for Target Tracking with Bearing Measurements Plus Known Speed

An underwater target tracking method applied in submarine,i.e,tracking a target with bearing measurements plus its known speed,is analyzed.Some unique properties are unearthed.System observability is examined and two necessary conditions for the system to be observable are obtained. Two possible modeling perspectives are introduced and a wide-spreading modeling mistake,which makes the known target speed ineffectual,is revealed.The multi-solution problem for the target course is discussed,and it is indicated...
