Multi objective overlay is a new comprehensive concept that satisfies multiple constraints and performance metrics while having multiple objective functions independent of the system and is widely used in many fields such as military,aerospace and industry.At the same time,it can meet various requirements for system resources and security in different situations.Firstly,the application of data analysis method in UAV network layout method is analyzed,which mainly performs data screening,data pre processing,decision tree classification on the collected data,and then plans the UAV network by decision tree classification.Secondly,the multi objective coverage model of UAV sensors is introduced and two commonly used models are presented.Finally,the multi target coverage UAV network layout method based on data analysis algorithm is investigated.
