[0002] The infrared target simulator is one of the important detection and calibration devices frequently used by infrared system engineering and technical personnel. Its accuracy and performance stability will be directly related to the main technical indicators and performance of infrared series products. The target is a key component of the infrared target simulator. The target is located on the focal plane of the simulator collimator, so that the photoelectric system to be tested receives a parallel light beam close to that of an infinitely far target, and the target presents a pattern with a certain contrast on the video image of the thermal imager or low-light night vision device. Based on this, the main performance parameters of the infrared complete product are detected.

[0003] When an existing infrared target simulator tracks a dynamic target, the activity range of the infrared target simulator is limited, so that the infrared target simulator has an insufficient angle range when tracking the target and is prone to losing the tracked target, resulting in poor flexibility of the infrared target simulator.

[0004] Therefore, those skilled in the art provide a dynamic tracking infrared target simulator to solve the problems raised in the above background technology. Utility Model Content
