Abstract

A pneumatic optical infrared imaging target simulation system based on a five-axis rotary table is applied for tests of infrared imaging detection guidance systems for a high-speed aircraft in the atmosphere and to the field of semi-physical simulation. In order to overcome the shortcomings of the existing infrared imaging target simulation systems for the aerodynamic optical effect simulation capability, according to the principle of optical conversion, a pneumatic optical effect loaded on the equipment under test is converted into the infrared imaging target simulation system, only through software calculation, a dynamic infrared target scene containing a pneumatic optical effect in the original infrared imaging target simulation system can be generated. The pneumatic optical infrared imaging target simulation system can simulate verification of effects and evaluation of the effect of aerodynamic optics on the infrared imaging detection guidance system.

Description

technical field [0001] The invention relates to the field of testing and hardware-in-the-loop simulation tests for infrared imaging detection and guidance systems of high-speed aircraft in the atmosphere, especially the five-axis turntable-based system that can be used to verify the influence and evaluation of aero-optical effects on the performance of infrared imaging detection and guidance systems. Aero-optical infrared imaging target simulation system. Background technique [0002] As the aircraft with the optical imaging detection and guidance system flies at high speed in the atmosphere, a complex flow field is formed between the optical hood and the incoming flow, which will cause heat, thermal radiation and image transmission interference to the optical imaging detection system, causing the target image to be biased. Shifting, shaking, blurring, this is the so-called aero-optic effect. [0003] The aero-optical effect is an effect that occurs on the optical imaging d...
