A digital multi-beam phased array antenna device for ad hoc network communication

Abstract

The invention discloses a digital multi-beam phased array antenna device for ad hoc network communication, which belongs to the technical field of wireless communication and antennas. The device comprises an antenna array plane, a coupling calibration network, a double-channel intermediate frequency digital TR assembly, an intermediate frequency acquisition processing module, a digital multi-beamforming processing module, a beam control module, a modulation and demodulation unit, a clock and synchronization network, a local oscillator and local oscillator power division network and the like.The antenna device adopts high-gain directional narrow beam transceiving, has high capacity, high speed and good anti-interference and anti-interception capabilities, has a flexible simultaneous multi-beam forming capability, and can communicate with a plurality of targets at the same time. In actual use, the number of wave beams can be flexibly increased by modifying a signal processing algorithmunder the condition of not increasing hardware resources, and the system expansion capability is high. The performance of an ad hoc network communication system is improved, and the application rangeof an ad hoc network communication product is expanded.

Description

technical field [0001] The invention belongs to the field of wireless communication and antenna technology, in particular to a digital multi-beam phased array antenna device for ad hoc network communication. Background technique [0002] Ad hoc network communication usually uses omnidirectional antennas to complete the transmission and reception of electromagnetic waves. The advantage of omnidirectional antennas is that signals can be received in every direction, but its disadvantages are low antenna gain, poor anti-interference and anti-interception capabilities; strict restrictions Ad hoc network communication system application promotion. [0003] The existing ad hoc network communication system needs to be further improved in terms of gain, anti-jamming, and anti-interception capabilities. Insufficient capabilities in these areas will limit the performance of the ad hoc network communication system, and limit the communication distance and communication capacity of the s...
