Research On Static Characteristics Of Projectile Radiation Simulator

As one of the field testing equipments of projectile parameters, the sky screen has been widely used in field testament with its high precision and repeatability in measurement. These properties of sky screen will changed with the illumination in the field. In order to make the test reliable, the IR techniques has been explored by using of the radiation simulator and related parameters of the projectile. The infrared radiation characteristics of the projectile in flight are studied and its research results can be used to build up the measurement set and a basic research platform for the applications around infrared detection technology.Projectile radiation simulator (PRS) contains three main parts:elema as infrared radiation source, rotating mirror and electronic control unit. Simulation experiment of the projectile flight and associated with related experiments such as senor experiment, system calibration etc can be implemented with the PRS. This paper focuses on the following aspects:1) By simulating the infrared radiation characteristics of three kinds of typical projectiles, the basic engineering parameters are determined; 2) According to the simulation results, selecting infrared radiation source, designing the mechanical structure and electric control unit are made; 3)The appropriate infrared detector is selected, the signal detection circuit and the device structure are designed by using of simulation results; 4) The detection stability and the detection range are analyzed; 5) Experimental platform is set up to verify the feasibility of the PRS to the projectile of flight.Through the simulation of infrared radiation characteristics of projectile analysis, peak wavelength located in the wavelength between 3/m to 6μm. In this case the infrared radiation source of the projectile is designed and the static test is carried out. The experimental results show that the detection range is in the range of 60mm to 340mm, and the distance from the radiation source the to test place is from 180mm to 200mm. The stability of the system in the 60min standard deviation is 0.82. The flight projectile radiation simulator can be used to simulate testment of the flying projectile.
