Abstract

The invention discloses an infrared and visual light combined guidance semi-physical simulation method. The method includes the following steps that an infrared and visual light combined simulation system is built; a dual-target load type five-axis rotary table overall structure is determined; the layout and load installing mode of the infrared and visual light combined simulation system are determined; infrared and visible light double wavebands operate in a segments in a combined mode. The infrared and visual light combined guidance semi-physical simulation method effectively meets the requirement of large-diameter infrared and visual light combined seeker double waveband segmented combined guidance semi-physical simulation tests.

Description

technical field [0001] The invention relates to a semi-physical simulation method for infrared and visible light composite guidance, in particular to a semi-physical simulation method for a large-caliber infrared and visible light composite seeker dual-band segmental composite guidance semi-physical simulation method. Background technique [0002] Existing hardware-in-the-loop simulation methods for optical guidance generally use a three-axis turntable + two-axis turntable (a three-axis turntable + two-axis turntable constitutes a five-axis turntable) + a direct projection scheme of a target simulator. Whether the large-aperture target simulator is used in the hardware-in-the-loop simulation of infrared and visible light composite guidance mainly depends on whether the aperture of the infrared and visible light composite seeker is large. [0003] For the hardware-in-the-loop simulation test of the large-caliber infrared / visible light composite seeker, if the existing method ...
