System and method for achieving full-aperture wide-angle receiving and transmitting beam of phased-array antenna

Abstract

The invention discloses a system for achieving a full-aperture wide-angle receiving and transmitting beam of a phased-array antenna. The system comprises a plurality of antenna arrays, a plurality of T / R assemblies, a multichannel transceiver, a beam parameter base and a beam controller, wherein the T / R assemblies are used for conducting amplitude and phase weighing on transmitted and received signals, the multichannel transceiver is used for conducting uniform amplitude and phase distribution on the emitted signals and uniform amplitude and phase synchronization on the received signals, the beam parameter base is used for storing amplitude and phase parameters corresponding to a formed full-aperture wide beam shape, and the beam controller is used for calling amplitude and the phase parameters and sending the amplitude and the phase parameters to the T / R assemblies according to receiving and emitting pointing information input from the outside. Meanwhile, the invention further discloses a method based on the system. By means of the system and the method, transmitting and receiving involving all the arrays are achieved in a wide angle range in a mode of amplitude and phase weighing, and the limitation that a conventional phased-array antenna system only can conduct transmitting and receiving with high directivity is eliminated, so that the utilization rate and uniformity of the receiving and transmitting units (namely the T / R assemblies) are increased.

Description

technical field [0001] The present invention relates to the technical field of broadband radio communication of large-scale fixed or mobile platforms at sea, in particular to a system and method for realizing full-aperture wide-angle transceiver beams of phased array antennas, which is suitable for applications that need to be transmitted between the broadcast transmission mode and the directional transmission and reception mode. Application systems that can be quickly switched between, such as offshore broadband data networks that work in TDD mode, broadband access systems for offshore operating platforms, etc. Background technique [0002] Large offshore platforms include two types, one of which is a relatively fixed offshore engineering platform such as an oil drilling platform, and the other is a large mobile surface ship. The wireless communication system composed of these nodes has the characteristics of time-varying network topology, and the carrying platform is const...

Problems solved by technology

The price of doing this is that on the one hand, the capabilities of most transceiver units (i.e., T / R components) in the array are not utilized; The gain reduction caused by the reduction, and the need to use two kinds of transceiver components with different power capacities, brings about a series of problems such as interchangeability, process consistency, and cost control.
