Multifunctional high-power phased array system

Abstract

The invention discloses a multifunctional high-power phased array system, which comprises a plurality of phased array power units, and each of the plurality of phased array power units comprises two groups of switch phase shifters, radio frequency channels and power amplifiers, wherein the phased array power units are connected with one another; the two groups of switch phase shifters are connected with each other and then are connected with the radio frequency channel, and the radio frequency channel is connected with the power amplifier; wherein each of the two groups of switch phase shifters comprises a radio frequency switch and M phase shifters, M is a positive integer, and the radio frequency switch is connected with the phase shifters. According to the invention, the complexity of the phased array system architecture is effectively reduced, the physical size is reduced, and the implementation cost is greatly reduced; in this way, the functional links and channels can be flexibly configured; when multiple functions are achieved at the same time, power devices or radio frequency links do not need to be additionally arranged, and time-sharing use of the multiple functions or simultaneous use of the multiple functions in different areas can be met only by replacing selection of the phase shifters.

Description

technical field [0001] The present application relates to the field of phased array technology, in particular to a multifunctional high-power phased array system. Background technique [0002] With the rapid development of phased arrays in the field of military and civilian 5G base stations such as communications, radar, and electronic countermeasures, the demand for multifunctional phased arrays from large platform equipment is becoming more and more urgent. Among them, the performance, cost and physical Composition complexity becomes the most important consideration in system design. Because when the phased array realizes a single function, the number of links and parts it consists of is huge, resulting in huge cost and physical size. In order to realize the multifunctional phased array, it will inevitably lead to an increase in the volume and cost of the equipment load. [0003] The traditional multi-functional phased array system is to install multiple independent sing...

Problems solved by technology

[0003] The traditional multi-functional phased array system is to install multiple independent single-function phased array devices. Because the phased array has a great impact on space, the current multi-functional phased array is used in time-sharing. Sometimes (such as communication functions), other functions such as radar and electronic countermeasures of the entire system will avoid using time slots, which leads to idle physical equipment and huge waste of cost
