The Design And Realization Of Ectro-optic Countermeasure Device Simulation Test System

Electro-optic countermeasure simulation experiment is one of important approaches to evaluate the performance of electro-optic weapons scientifically and rationally. Utilizing technology such as computer and simulation, the thesis has designed and realized an electro-optic simulation test system, aiming at the work course of the laser semi-active homing weapons. The system could accomplish dynamic hardware-in-loop simulation and aviation experiment.The system could accomplish electro-optic countermeasure hardware-in-loop dynamic simulation test and has offered a platform for the validation and performance evaluation of the electro-optic countermeasure equipment It has important military significance and application value.On the basis of analyzing the principle of high frequency laser directed jamming, it has set up a electro-optic countermeasure simulation test system by meansof modularize structure design. Through the research of the prinaple of laser semi-actine homing,it has analysed and put forward the main performance target and desigh principle. In order to solve the problem of detecting accuracy, it adopt high accuracy detector, S5981, to detect and transform laser singral. According to weak source signal、strong noise counter to detecting distance, it adopts amplifying device of low noise and broad frequency,which solved the question of weak signal amplifying by several grades amplifying and back amplifying method. According to anti-jamming method of laser homing head, the system adopted methods to set pulse gate in electronic route so as to make simulated homing head acquire higher reliability.It has designed and realized simulant laiser homing head, which has the function of collecling magnifying and processing the laser signal. Furthermore, it has designed the software and realized the real-time imputing data, reproducing the flight path, according to the demanding of simulation test system.It has provided the evidence to the effectiveness evaluation of electro-optic countermeasure device.It is indicated that each part of the system works stably and has good compatibility through dynamic and statistic experiment. It is tested that simulant laser homing head has reached the designed target and adapted to long-distance fieldwork.
