| The data fusion algorithm is used in the laser / radio fuze to reduce the interference from the natural environment and human beings.This paper takes the laser / radio fuze as the research object.Aiming at the interference from the ground and sea,the chaff echo and the cloud echo which may be received by the laser guide,the environment modeling technology of the fuze is studied The visual simulation software of fuze warhead cooperation is developed to analyze the control performance of the fuze when it is disturbed by the environment.The main work is as follows:A three-dimensional environment suitable for environment echo simulation is developed.It includes building the ground model with LOD technology,building the sea scene based on Gerstner wave theory,and building the air motion model of chaff cloud and cloud with particle system technology.The hidden situation of ground,sea and chaff scattering unit in fuze detection field is analyzed.The echo simulation technology of radio fuze ground,sea and chaff is studied.The surface and sea echo are calculated by the panel method,and the characteristics of the surface echo and sea echo under different sea conditions are analyzed.For the chaff cloud,the RCS is calculated from the two stages of the existence of mutual occlusion and the negligible of mutual occlusion,and the echo of chaff cloud under various conditions is analyzed.The cloud echo simulation technology of laser fuze is studied.Based on Mie scattering theory,the cloud echo of laser fuze is calculated by improved Monte Carlo simulation method,and the simulation results are analyzed.Based on the laser / radio compound fuze and the rod warhead,the simulation software of fuze warhead cooperation is developed.The algorithm of fuze detection and start-up and the calculation of the life point parameters of the rod warhead are studied.The influence of the explosion point control error on the hit situation of the warhead under the condition of environmental interference is analyzed. |
