Embodiment Construction

[0031] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses a system allowing for phased-array amplitude weighting. The system is applied between an external circuit and a target system and comprises a wave beam generation module and a phased-array antenna module. The wave beam generation module is coupled with the external antenna and the phased-array antenna module. The phased-array antenna module is coupled to the wave beam generation module and the target system. The problems of lowering side lobe level in a phased array, lowering cost and facilitating implementation are solved by the use of the system.

Description

technical field [0001] The invention relates to the communication field, in particular to a system capable of realizing phased array amplitude weighting. Background technique [0002] With the development of science and technology, modern transportation tools are becoming faster and faster, and it is becoming more and more difficult for communication antennas in the form of mechanical scanning to adapt to real-time tracking of high-speed moving target systems. The phased array antenna replaces mechanical scanning with electronically controlled scanning, which improves the tracking speed of the antenna to the target system, and is also the development direction of the current communication antenna. [0003] In the prior art, with the increasingly widespread application of the phased array system, the sidelobe level has become a very important indicator. Among them, the ratio of the maximum value of the side lobe to the maximum value of the main lobe is called the side lobe l...
