The Torpedo Homing System Simulation Mathematical Simulation

This thesis considers the research of simulation modeling and simulation system of homing system, which can not only investigate the performance, theory and method of homing system, but also improve the homing system technique.In the ocean battlefield, the submarine and submarine army threaten the naval vessel above water and nearly bank goals constantly. It is the main content of the sea warfare in the future to assault submarine. Torpedo is the only useful weapon and play very important role during naval battle. Homing torpedo is part and parcel of weapons working under water.The main research advances can be summarized as follows:(1) Study the signal processing's performances and methods of homing torpedo system comprehensively, in order to setting up a corresponding mathematical models;(2) Analyze the ocean channel's effects on the work of homing system, then found some models such as target echo signal, noise (including background noise, target radiating noise, etc), ocean reverberation. According to them, simulate the array signal;(3) The system structure, every function blocks composing are studied and founded thoroughly. Then, discuss methods of signal processing in time domain and airspace domain;(4) Program the simulation software of torpedo's homing system according to the simulation models and flow charts, which connected with torpedo's control part.
