Crawling Sub Munitions Ad Hoc Network Technology

The challenge of modern warfare has made the research of information cooperative and network coordinated operation between ammunition weapons systems more and more concerned.On entering the target area of the vehicle,the enemy aircraft and other military equipment to blockade the cooperative attack,can effectively weaken the enemy’s combat capability,slowing its military mobilization and deployment,strive for more time for our military operations,to seize the initiative in wartime.In this paper,the main research of crawling sub-ammunition ad hoc network technology for the regional blockade is one of the important contents of the intelligent network blockade warhead technology.Crawling submunition and the composition of cooperative combat system of ad hoc network is introduced,and the cooperative combat flow is determined.According to the principle of ZigBee wireless ad hoc network,based on Digi’s XTend RF module for ad hoc network communication research,the definition of collaborative combat process blocking information,and coding and packaging.Based on the comparison of different location methods and the background of practical applications,this paper studies the ranging algorithm based on received signal strength(RSSI)and the trilateral positioning algorithm to realize self-localization of crawling submunitions,and mixes and optimizes the obtained RSSI values,reduce the ranging error,improve positioning accuracy.The experiment proves the communication and location technology of ad hoc network in this paper.Node communication,multi-node network communication,relay communication,maximum distance communication,blocking information packet communication test and RSSI hybrid filtering optimization results show that,based on the principle of ZigBee,XTend self-organizing network communication satisfies the background requirement of this topic,and the positioning error based on RSSI ranging and trilateral positioning method is less.
