Abstract
Millimeter-wave/infrared beam combiner is a pivotal device in the composite guidance hardware-in-the-loop(HWIL) simulation system. It has the dual characteristics of reflecting millimeter-wave and transmitting infrared. In this paper, millimeter-wave reflection estimation model and infrared transmission model of metallic mesh are proposed to design a parabolic beam combiner of metallic mesh. The optical properties of millimeter-wave reflected optical path and the imaging resolution and signal-to-noise ratio of infrared transmission optical path based on parabolic metallic mesh are studied respectively. Simulation results show that the system structure is compact, imaging resolution is close to the diffraction limit, the infrared transmission rate and signal-to-noise ratio can be increased by reducing line width of mesh. The design results provide a theoretical reference for the research of the millimeter-wave/infrared dual-mode guidance HWIL simulation system.
