Abstract

The embodiment of the invention discloses a broadband beam synthesizer with a gradient-gradient dielectric constant. The broadband beam synthesizer comprises a gradient-gradient dielectric constant layer and an infrared reflecting layer, the air bubbles are doped in the dielectric constant gradient gradual change layer to change the dielectric constant, a dielectric constant Gaussian gradual change function is provided, the microwave transmittance of more than 80% at the frequency band of more than 10GHz is obtained, the technical effects of large microwave transmission bandwidth and high transmittance are realized, and the microwave transmission efficiency is improved. The problem that the beam synthesizer is required to have large bandwidth and high transmittance during simulation tests of tested equipment of different wavebands in a composite guidance semi-physical simulation test is solved. The microwave power transmittances of vertical polarization and parallel polarization of the beam synthesizer at an incidence angle of 45 degrees and a frequency band of more than 10GHz are both greater than 80%, further, the microwave transmittances reach 90% when the incidence angle is 0 degree and the frequency is greater than 10GHz, the technical effect that the surface type is not distorted is also realized, and the problem that the surface type deformation affects the infrared imaging quality is solved.

Description

technical field [0001] The present application relates to the technical field of microwave devices, and more specifically, the present application relates to a broadband beamformer with a gradual change in dielectric constant. Background technique [0002] With the development of jamming and countermeasure technology, single-mode guidance technology is difficult to meet the development of precision-guided weapons, and multi-mode composite guidance technology has become the mainstream because of the advantages of multiple guidance methods. The composite guidance hardware-in-the-loop simulation technology is used to simulate the performance and function of the composite guided weapon in the laboratory environment. The beamformer is a key component of the composite guidance hardware-in-the-loop simulation system, which is used to synthesize the microwave signal and the infrared signal at the same aperture. For beamforming methods that transmit microwaves and reflect infrared, ...
