Trust Region Optimization Method for Single Hydrophone Passive Ranging

doi:10.3969/j.issn.1000-1093.2012.09.017

Abstract

Abstract: In order to solve the problem of single hydrophone passive ranging, a method of Doppler passive ranging based on trust region optimization method was proposed. Compared with the existing method that has to detect the time and frequency when the target arrives to the course shortcut, the new method can detect the target in real-time detecting before it arrives to the course shortcut. This approach can obtain not only the kinetic parameters but also the current and predicted distances of the target. It makes full use of the target's Doppler information, and realizes real-time ranging for moving target by single hydrophone. It can also be suitable for the uniformly accelerated target model and has better practice value. Simulation results show its correctness.

Key words: information processing, single hydrophone, Doppler frequency, trust region optimization method, passive ranging
