Semi-physical simulation and performance certification system for laser proximity fuze

In order to consummate the evaluating system of the laser proximity fuze, a repeatable and quantitative method is provided for testing and betterment of the laser fuze, and a comprehensive simulation of the battle environment is achieved.The framework, principium and key technique of the semi-physical simulation and performance certification system for laser proximity fuze were introduced. The super-speed rail and carriage controls were used to simulate the meeting process of the missile -target encounter. The target and background simulation equipment were adopted to simulate the battle environment of the laser proximity fuze. The signal acquisition and analyzing equipments were applied to validate the performance of the real swatch. FPGA platform was used to simulate the signal processing circuit and the arithmetic of the laser fuze. The simulation platform was established to develop virtual design of the laser fuze. Most of the key problems of the system had solved, such as high speed signal acquisition equipment, laser echo simulation equipment and mathematical models of the laser fuze simulation platform. It also can overcome several drawbacks such as the low repeatability and the high expenditure of man power and material.
