Problems solved by technology

As the number of radio frequency nodes increases, the amount of data transmitted by radio frequency nodes increases in a quadratic relationship with the number of radio frequency nodes, which is very unfavorable for battery-powered radio frequency nodes, and will greatly shorten the battery life of radio frequency nodes

Abstract

The invention provides a target locating and tracking method based on a high-effect radio frequency network. The radio frequency network comprises at least two nodes. The nodes are distributed around a monitoring region and form more than two directed links. Each node sends a first message to a base station, wherein the first message includes a base station identification number, a sending node identification number and a receiving node identification number, and an attenuation link is formed by the sending node identification number and the receiving node identification number. By the high-effect radio frequency network, energy loss can be reduced and service life of the nodes can be prolonged.

Description

technical field [0001] The invention relates to the technical field of target detection and tracking, in particular to a target positioning and tracking method based on a high-efficiency radio frequency network. Background technique [0002] The RF node network utilizes RF nodes to locate and track targets. The target positioning and tracking technology based on the network of RF nodes does not require the target to carry any device, and it only needs the Received Signal Strength (RSS) value provided by the RF nodes. [0003] In the traditional working mode of the radio frequency node, the radio frequency node directly sends the RSS values ​​of all links formed by other nodes and the node to the base station node. As the number of radio frequency nodes increases, the amount of data transmitted by radio frequency nodes increases in a quadratic relationship with the number of radio frequency nodes, which is very unfavorable for battery-powered radio frequency nodes, and will ...
