Description

technical field [0001] The invention relates to the fields of hardware-in-the-loop simulation, detection, remote sensing, and spectrum analysis, and in particular relates to a radio frequency / optical composite target simulation device and method. More specifically, it relates to a compact field radio frequency / optical compound target simulation device and method with conformal design. Background technique [0002] In the field of precision guidance and detection, compound guidance and detection systems are being used more and more because of their longer range, higher precision and stronger anti-interference ability. In order to verify the performance of the guidance system, the method of semi-physical simulation is often used to test and verify the guidance and detection system. The core component of the hardware-in-the-loop simulation test is the composite target simulator, whose main function is to simulate the radio frequency and optical physical signals emitted by the ...

One of them is a composite method of infrared and microwave beam synthesis method, device and system (201410483850.1). Infrared is transmitted through a metal grid whose curvature matches that of a paraboloid. The infrared imaging quality is poor and the energy utilization rate is poor, and the combination of infrared imaging and microwave cannot be realized. complex

And most of the public reports are composite signal output satisfying RF / optical co-aperture. There is no RF / optical composite device with sub-aperture contraction field or a composite device that satisfies both sub-aperture and co-aperture.
