Abstract

The invention relates to a digital-analog hybrid cylindrical phased array antenna for ad-hoc network communication, and belongs to the technical field of wireless communication and antennas. The antenna comprises an antenna array plane, n m-channel TR assemblies and an intermediate frequency acquisition processing module, a digital multi-beam forming processing module, a beam control module, a modulation and demodulation module and the like, and each channel of each TR assembly is provided with k output branches; the antenna array surface is composed of m*k*n antenna array elements which are arranged in a rectangular shape with the circumferential direction as the row and the axial direction as the column. The antenna array plane is equally divided into k areas in the circumferential direction, k branches of each channel of the TR assemblies are connected with k array elements located in different areas in a one-to-one correspondence mode, and the ith TR assembly is exactly connected with the ith array element in each area. The antenna has the advantages of large capacity, the high speed and good anti-interference and anti-interception capabilities, the performance of an ad-hoc network communication system is improved, and the application range of 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-analog hybrid cylindrical phased array antenna 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] At present, in the case that some special platforms (such as airborne) have strict requirements on the installation height of the antenna, in order to improve the performance of the existing ad hoc network communication system, improve the communication distance and communication capacity of the system, it is necessary t...
