Abstract

The invention proposes a large dynamic energy infrared target simulation system. The system is composed of a radiation source module, an optical system, a control module and supporting devices. The radiation source module includes a black body radiation source, a black body controller, a condenser lens, a light barrier, an attenuation film group and a light barrier group. The attenuator group includes attenuator A and attenuator B. The diaphragm group includes diaphragm A and diaphragm B. The optical system includes a relay optical lens and a collimating optical lens. The control module includes industrial computer (with reflective memory card and motion control card), I / O card, motor driver, servo motor, control cable and control software. The control module can control the change of the shape, size and energy of the target. The spectral characteristics of the radiation source are adjusted by adjusting the temperature of the black body through the black body controller.

Description

technical field [0001] The invention relates to an infrared target simulation system, which is used in infrared semi-physical simulation. Specifically, it relates to an infrared target simulation system with a large energy dynamic range. Background technique [0002] Infrared technology has always been one of the fastest-growing high-tech technologies, especially high-sensitivity infrared systems are currently a hot spot in research and application. Infrared hardware-in-the-loop simulation test has the advantages of being realistic, economical, controllable, and repeatable. It is the main means to simulate the working process of the infrared system and test the performance of the infrared system in the laboratory. The infrared target simulation system is a key component of the infrared hardware-in-the-loop simulation system. Its function is to generate real-time changing infrared target signals in the field of view of the tested infrared system and simulate the dynamic radi...
