Title Simulation Analysis of Encountering Tests of Radio Fuze
Abstract
The main test methods of fuze actuation and related theory are introduced. Through target modeling and design of simulation system, this thesis completes the calculation of the fuze's target radar cross section (RCS) and the analysis of Doppler ultrasound signal, and gives the simulation analysis of a rotation encountering tests.
Starting from the view of fuze-warhead coordination, the research on fuze actuation tests and simulation field at home and abroad is studied. Introducing the study of target’s near-field scattering characteristics , this thesis infers to the expression of physical optics method in Gordon face integral method of the plate, and analyses the basic ideas and general expression of method of equivalent current , and gives the Doppler ultrasound signal process of the pulse Doppler fuze system .
Several targets such as cube, standard ball, cruise missile, aircraft etc. are modeled based on AutoCAD 3D modeling software in this thesis. Based on C++ Builder 6.0 software environment, the target’s data is extracted and sorted , and a software is developed to calculate the RCS and Doppler ultrasound signal with Physical optics method (PO) and Method of equivalent current (MEC). Finally, the simulation computation of target's RCS and Doppler information of both traditional and rotation encountering tests is completed, and a comparative analysis of both is given.
