Abstract

The invention belongs to the technical field of information processing, and discloses an unmanned aerial vehicle cluster target number detection method based on multi-sensor data fusion, comprising the following steps: step 1, two sensors of a radar and a communication signal detector respectively obtaining unmanned aerial vehicle cluster target number values, and obtaining basic probability assignment of detection data; step 2, fusing the elementary probability assignment in the step 1 by applying a D-S evidence theory fusion rule, and outputting the fused elementary probability assignment; and step 3, performing judgment decision on the fused basic probability assignment, and outputting an unmanned aerial vehicle cluster target number detection result. The D-S evidence theory-based unmanned aerial vehicle cluster target number detection method provided by the invention effectively solves the problem of low reliability of unmanned aerial vehicle cluster number detection by a single sensor, can provide more accurate data support for unmanned aerial vehicle cluster detection and defense, improves the accuracy of cluster defense effect evaluation, and a more reasonable defense decision can be made.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a method for detecting the number of drone cluster targets based on multi-sensor data fusion. Background technique [0002] With the rapid development of cutting-edge technologies such as multi-agents and communications, research on UAV swarm defense has gradually become the focus of attention of various countries. The individual UAV swarm targets have the characteristics of weak signal characteristics, complex cluster shapes, and multi-terminal changes, which brings difficulties in detecting the number of UAV swarm targets, thus affecting the selection of defense strategies and the evaluation of defense effects. [0003] In the actual UAV swarm combat environment, the data obtained by a single detection sensor such as radar often has certain uncertainty, so it is necessary to fuse the data obtained by different types of sensors to eliminate the possibl...
