Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0018] as figure 1 As shown, the preferred embodiment of the infrared dynamic triangular target simulator of the present invention consists of a triangular target assembly 1, a circular interference assembly 2, a beam combiner 3, a collimating projection lens 4, a housing 5, a flange plate 6, and a computer control system 7 composition. Collimating projection lens 4 is prior art, contains variable power objective lens 4a and collimating objective lens 4b (seeing in it) Figure 4 ), the spectral range is 3 μm ~ 12 μm wide band. The beam combiner 3 is a flat germanium single crystal coated with a semi-transparent and semi-reflective optical film layer of 3 μm to 12 μm. The triangular target assembly 1, the circular interference assembly 2, and the beam combiner 3 are all located in the inner cavity of the housing 5, one side of the ...

Abstract

The invention relates to an infrared dynamic triangular target simulator, belonging to the technical field of infrared simulation. The simulator comprises a vertically-arranged triangular target assembly, a beam combiner, a horizontally-arranged round interference assembly and a collimation projecting lens, wherein the triangular target assembly is used for generating a triangular target with continuously variable size, light intensity and gesture; the round interface assembly is used for generating a round interface with continuously variable size, light intensity and position; and the triangular target and the round interface are respectively reflected and transmitted by the beam combiner and then projected to a tested infrared imaging guide head through the collimation projecting lens in parallel beams. According to the invention, the triangular target is used for simulating a marauding aircraft or missile, the round interface is used for simulating baits released by the aircraft or missile, not only the fidelity problem of the target simulator for simulation is solved, but also the simulation test evaluation precision of dynamic tracking and anti-jamming property of the infrared imaging guide head is improved.

Description

technical field [0001] The invention belongs to the technical field of simulation testing, and mainly relates to an infrared dynamic simulator, in particular to an infrared dynamic simulator with interference. Background technique [0002] The infrared imaging seeker is a passive guidance method, which has the advantages of all-weather and strong anti-interference ability. In order to shorten the development cycle of the infrared imaging seeker, it is necessary to use the infrared target simulator to simulate the dynamic tracking performance of the infrared imaging seeker in the laboratory. Usually, the infrared target simulator is installed on the two-axis motion simulator of the outer frame through the flange, and the infrared imaging seeker is installed on the three-axis turntable of the inner frame. The infrared target simulator simulates the radiation characteristics and dynamic characteristics of the target, and the two-axis The motion simulator simulates the yaw valu...
