Abstract
Microwave (MW)/Infrared(IR) dual-mode compound guidance technology has greatly developed recent years for enhancing guidance precision effectively. Here a new micro-mirror array structure is introduced as upright display for MW/IR beam combiner in HWIL simulation. The beam combiner is used in the IR/MW compound HWIL system for transmitting the MW signal while reflecting the IR signal. The spatial resolution and spatial uniformity are two important performance indicators for beam combiner in the application of HWIL simulation system. In this paper, the definitions, measurement methods, and results of spatial resolution and spatial uniformity are given. Through the measurement by multiple groups of black and white stripes, the spatial resolution and the spatial uniformity can be got. It shows the micro-mirror array beam combiner can be applied for MW/IR dual-mode common-aperture HWIL simulation system.
