Ultraviolet light cooperation multi-sensor data fusion unmanned aerial vehicle friend or foe identification method

Abstract

The invention discloses an ultraviolet light cooperation multi-sensor data fusion unmanned aerial vehicle friend or foe identification method, which comprises the following steps: dividing unmanned aerial vehicle target feature information obtained by a radar sensor, an ultraviolet light detection sensor and an ESM sensor into a training group and a test group, training a BP neural network through the training group, and verifying the correctness of the BP neural network through the test group; secondly, after unmanned aerial vehicle target feature information is input, enabling the BP neural network to automatically classify unmanned aerial vehicle target attributes, and using the IFF system and the BP neural network to obtain a target recognition probability; then, judging target attributes of the unmanned aerial vehicle by using a D-S evidence theory, and distributing corresponding weight values; finally, fusing the weight values obtained by the sensors and the IFF system, unifying friend or foe identification attributes, and obtaining an identification result. According to the method, the friend or foe identification is carried out by adopting multi-sensor data fusion, so that the obtained target information has higher resolution and reference, and a more accurate identification result is obtained.

Description

technical field [0001] The invention belongs to the technical field of identification of friend and foe, and in particular relates to a method for identifying friend and foe of an unmanned aerial vehicle through ultraviolet light cooperative multi-sensor data fusion. Background technique [0002] With the development of science and technology, modern warfare has turned into information warfare. Information warfare has the characteristics of suddenness, rapidity, integration of sea, land and air, and short duration. The combat environment is very complex. Both the enemy and the enemy need to use camouflage, concealment, deception, and interference to conduct identification and anti-identification contests. . [0003] Identification Friend or Foe (IFF) is to identify and confirm the friend-or-foe attributes of targets within the time and space required for combat through various available technologies and means, combined with general-purpose or dedicated platform equipment. ...

AI Technical Summary

Problems solved by technology

[0005] At present, the existing identification friend or foe system usually uses radio to transmit information, but considering the shortcomings of traditional radio communication due to safety and flexibility, it is likely to cause damage to the communication link in the case of strong electromagnetic interference, and then It is impossible to complete the identification of friend and foe. For this, it is necessary to use a more robust auxiliary information communication method for information interaction
