AI Technical Summary

Problems solved by technology

Although this structure is simple, there are many problems: it cannot simulate the infrared background, interference, and there is no collimation system; and because the axis of the infrared guidance device does not coincide with the axis of the turntable, parallax appears

However, the turntable and the infrared subsystem of the existing schemes are located outside the anechoic chamber, which requires a long exit pupil distance of the infrared simulation target, which makes the infrared simulation subsystem too complicated; and the test of the microwave / infrared common aperture equipment also brings many problems

[0014] In summary, the existing microwave / infrared dual-mode beamforming schemes have deficiencies, and do not solve the dual-mode hardware-in-the-loop simulation test in the laboratory environment well.
