Fast neighbor discovery method for double-area-array radar ad hoc network

Abstract

The invention discloses a fast neighbor discovery method for a double-area-array radar ad hoc network. The method comprises the following steps: firstly, obtaining a coarse position of a neighbor nodeby using an inherent scanning function of the radar; then, allocating a neighbor discovery scanning area according to the bidirectional transmission characteristics of a double-area-array phased array radar; and finally, fully utilizing the advantages of the double-area-array phased array radar to reasonably schedule two area-arrays to cooperatively work, performing deep scanning in a scanning interval, and achieving neighbor discovery in the whole network in a secondary handshake manner. By adoption of the method disclosed by the invention, neighbor discovery can be achieved efficiently andquickly in the background of the double-area-array radar ad hoc network.

Description

technical field [0001] The present invention relates to the field of radar communication, in particular, a fast neighbor discovery method——Scan Based Algorithm for Double-Face Phased Array Radar Communication Integrated Node Neighbor Discovery Algorithm (SBA-DPAR, Scan Based Algorithm for Double-Face Phased Array Radar ). Background technique [0002] Neighbor discovery is the basis for obtaining network topology information and realizing communication between nodes, and improving the speed of the neighbor discovery process is the key to completing fast network construction. According to the transmission mode, neighbor discovery can be divided into omnidirectional neighbor discovery and directional neighbor discovery. Omnidirectional neighbor discovery uses omnidirectional antennas for transmission, which can cover all angles at the same time. The discovery process is relatively simple, but the transmission distance is short and it is prone to interference, such as hidden t...

Problems solved by technology

However, due to the directivity of directional transmission, the angular range of scanning at the same time is limited, and for pure directional antennas, only when the transmitting and receiving beams are aligned with each other and the transmitting and receiving patterns match can they find each other. The probability of finding neighbors is low

[0003] At present, there are few studies on neighbor discovery using the advantage of radar scanning information of phased array radar, and there are almost no studies on neighbor discovery using two beams of double-sided array phased array radar. The existing neighbor discovery algorithms cannot be directly transplanted. In the scene of double-sided array phased array radar, it cannot give full play to its advantages
