Embodiment Construction

[0025] The advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0026] refer to figure 1 , shows a solid surface reflector 100 for transmitting space microwaves. The reflector 100 is part of the antenna. When the antenna receives electromagnetic waves, the reflector 100 focuses the incident electromagnetic waves to the feed element for reception. When the antenna emits electromagnetic waves, the feed element emits the electromagnetic waves to the reflector 100 and the reflector 100 reflects the electromagnetic waves into space. The solid surface reflector 100 is a kind of reflector 100 , which specifically includes: a reflective surface 110 , a first grid 120 and an actuator 130 . specifically:

[0027] - The reflective surface 110 is the carbon fiber composite material panel at the front of the solid surface reflector 100. If the frequency of the transmitted electromagnetic wave is l...

Abstract

Provided in the present invention is a solid-surface reflector for microwave reflection, the reflector comprising: a reflective surface provided on a panel in the front of the solid-surface reflector; a first grating exhibiting a supporting structure that projects from one side of the reflective surface and separates the reflective surface to form at least one grating unit; and at least one actuator fixed onto the first grating to control the geometry of the reflective surface. The invention can adjust and control the profile accuracy of the reflective surface by using the described technical solution. On the basis of the existing molding process and processing accuracy, and by combining the described technical solution, the invention can improve the profile accuracy of the reflective surface of the solid-face reflector. Meanwhile, the invention can save manufacturing costs, and reduce process complexity and technical implementation difficulty.

Description

technical field [0001] The invention relates to the fields of microwave communication and microwave observation, in particular to a solid surface reflector for microwave reflection. Background technique [0002] Solid surface reflectors are widely used in space microwave communication and space microwave observation. The existing commonly used solid surface reflectors do not have the function of active control of surface precision. However, with the continuous development of space observation and communication technology, the frequency and power requirements of microwave communication are getting higher and higher. Therefore, the requirements for surface accuracy of large-diameter light-weight solid-surface reflectors are also continuously increasing. At present, basically by improving the manufacturing accuracy of the reflector and the thermal stability of the material, the system's requirements for the on-orbit surface accuracy of the solid surface reflector are met. ...
