Design and Implementation of Active Omnidirectional Sonobuoy Simulation System

Base on the working principle of active omnidirectional sonobuoy, this paper analyzes the ranging and speed measurement based on the modeling of single active omnidirectional sonobuoy and the positioning algorithm of multiple active omnidirectional sonobuoys. The reason for the error in the algorithm and the method to reduce the error are given. A calculation method of the approximate course and speed of the target based on the active omnidirectional sonobuoy array is deduced. Designed and implemented a simulation software system for active omnidirectional sonobuoy detection, and simulation experiments are carried out. The results show that the system can achieve the target information solution, and the error is within the acceptable range.
