Research On The Key Technology Of Appearing Rapidly Targets

Fast looming target is a device that tests the reaction speed of the heavy weapon system and has great significance in researching and designing it in weapon testing field. "Shutter" mode of the fast looming is introduced in this paper. The relationship of visual area and the effect distance can be obtained through resolution of the observation system and the detection method of discourse analysis by human eyes, binoculars and night vision system when the target area is fading. On this basis, a slider-type, channel type, and cam-type mechanical transmission structure is designed and their advantages and disadvantages are analyzed. Finally, emissivity of the object is measured and the measurement results are analyzed by doing an experiment.The experimental method is used to analyse the infrared radiation characteristics of the target element in fast looming target to obtained the general radiation laws of the target element.
