Radio-frequency holographic transmission/light reflection type common-caliber composite plane wave field simulation device

Abstract

The invention discloses a radio-frequency holographic transmission / light reflection type common-caliber composite plane wave field simulation device comprising a radio frequency feed source, a plane transflective mirror, a light source and a collimating lens. The phase center of the radio frequency feed source is arranged at the focal point of the plane transflective mirror. The light source is arranged at the focal plane of the collimating lens. A radio-frequency beam emitted by the radio frequency feed source is irradiated on the plane transflective mirror; the beam enters the plane transflective mirror and then is transformed into a plane wave based on a radio frequency calculation holographic structure; the light source is collimated into parallel light by the collimating lens; the parallel light is reflected by an optical reflection membrane mirror surface of the surface of the plane transflective mirror; and the reflected light and the transmitted radio-frequency beam form a composite plane wave field. According to the invention, the advantage of composite plane wave field forming by the traditional beam combiner and structure is absorbed. The simulation device has advantagesof simple and compact structure and high integration degree.

Description

technical field [0001] The invention relates to a radio frequency / optical co-aperture composite signal simulation device, in particular to a radio frequency holographic transmission / light reflection type co-aperture composite plane wave field simulation device, which belongs to the intersecting field of radio frequency and optics. Background technique [0002] Since the RF / optical composite system can combine the characteristics of RF and optical systems at the same time, it can realize the complementary advantages of the two electromagnetic bands, and is increasingly used in civilian and military fields such as composite detection, composite guidance, and composite communication. Also because the RF / optical co-aperture composite system spans the two electromagnetic bands of RF and optics, it is difficult to conduct RF and optical testing and simulation of the system simultaneously in the laboratory. It is necessary to simulate plane waves from infinity in the limited space ...
