Distributed Detection Fusion Algorithms of Automatic Chemical Agent Detector Alarm
Jin Gu, Xuezheng Zhu · 2017
Whenever a chemical toxic agent attacks, there needs an accurate inspection to send alarm signals for the crew and protection equipment.Given the detection rate of single toxic agent warner is easier affected by the surroundings, the author has conducted a fusion algorithms on the principles of Bayes test and has confirmed that the false dismissal probability and false-alarm probability will decrease sharply after the fusion by numerical test.Around a battlefield, the existence of a chemical attack forms the foundation of a chemical reconnaissance and protection.In other words, a precise judge of an uncertain chemical attack is rather important for the army to maneuver.Considering the current unsatisfying technique and more disturbing battlefield elements, single alarm has an undoubtedly weakness of false dismissal and false alarm.This distributed detection fusion technique allows every alarm send their detections around the location and the fusion center is able to make a general decision under a certain optimization principle according to the detections from every corner, which permits the detection range becoming wider and detection rate lower.
