摘要: 目前水下目标运动分析(TMA)基本上以目标作匀速运动为前提进行研究,而少有以目标做匀加速运动为前提的TMA解算研究。提出一种在观测平台不机动时求解匀加速直线运动目标参数的内点-Levenberg-Marquard解算方法,并结合多普勒效应双模型与解算方法,提出一种参数搜索优化方法,使得求解参数的过程快速收敛。仿真结果表明,所提解算方法能够有效地求解匀加速直线运动目标的运动参数,并且降低了对本艇机动的依赖程度。

Abstract: The most research on target motion analysis (TMA ) of underwater target is based on the hypothesis of uniform motion of a target, but is seldomly based on the hypothesis of uniformly accelerating motion. An innerpoint-Levenberg-Marquard (LM) method of calculating TMA parameters without the motion of observation platform is proposed. And an optimization searching method for TMA parameters is proposed, which combines the Doppler effect double model and the solving method of TMA parameters. It makes the solving process of parameters converge quickly. Simulated result shows that the inner-point LM method can be used to solve the TMA parameters effectively and reduce the dependence on the motion observation platform. Key
