Problems solved by technology

[0005] Existing perception systems using linear array antennas can only generate two-dimensional beams, that is to say, they can only be used in scenes with two-dimensional motion properties, which limits the application range of UAV perception

Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] In the prior art where the communication system and the sensing system are independent of each other, the power of the radar detection equipment, that is, the sensing system transmits signals is often as high as hundreds of watts or even thousands of watts, and the out-of-band spurs can reach the order of watts. However, the received signal power of an independent communication system is usually only on the order of milliwatts. As such, communication sy...

Abstract

The embodiment of the invention provides an array antenna, a beam forming method and a sensing and communication integrated system, and the array antenna based on the integration of sensing and communication comprises a sensing sub-array and a communication sub-array. The sensing sub-arrays are used for generating three-dimensional sensing wave beams so as to realize a sensing function in the sensing and communication integrated system; and the communication sub-array is used for generating two-dimensional communication beams so as to realize a communication function in the perception and communication integrated system. Therefore, the application range sensed by the unmanned aerial vehicle can be expanded.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an array antenna, a beamforming method and an integrated system of perception and communication. Background technique [0002] The existing UAV inter-swarm perception information fusion scheme adopts a mode in which the communication system and the perception system are independent of each other. Specifically, the perception system and communication system use independent radio frequency antennas, radio frequency links, digital processing equipment and other system equipment. Each drone in the drone swarm has a perception system and a communication system. [0003] The perception system forms beams to perceive the surrounding environment, and performs perception data processing in the data processing equipment in the perception system. When the perception result data needs to be fused, the perception system sending the UAV passes the perception result data through ...
