Abstract

MMW/IR compound target simulation system can provide realistic millimeter and infrared signals in the occasion of performance verification for MMW/IR compound guidance missile. A reflector antenna arrangement with MMW/IR bispectral window is proposed for the MMW/IR compound target. Well, the edge diffraction of reflector which can cause angle measurement error seriously influences the uniformity of electric field. In order to enhance the accuracy, two reflector edge processing methods were given in this paper. Through the numerical calculation and comparison, the accuracy of angle measurement can be to 0.032° at 35 GHz. The edge processing can well oppress the edge diffraction and improve the uniformity of MMW field. And the edge processing can be used in the engineering of compound target simulation system design and development for HWIL simulation.
