The Design And Implementation Of The Upper Computer Software Of The Distributed Networked Radar Based On The Electronic Map

In order to effectively combat and defend against targets in real time,it is necessary to combine multiple sensors to provide target information and accurately track them,in the face of the high maneuverability and complexity of enemy flying targets in modern battlefields,.At the same time,the multi-sensor geographical location layout information and the detected target information are visually displayed on the host computer,which plays a vital role in grasping the overall situation of the entire battlefield.This dissertation combines the actual engineering project,using information fusion technology and electronic map technology to achieve the acquisition,processing and display of track data and the visualization of radar information,and has carried out a series of debugging verification.Firstly,the QT UDP multicast communication technology is introduced.Through the application of this network communication technology,the many-to-one data transmission mode inside the networked radar is realized.In the process of data transmission,the format of the custom data transmission solves the problem of distinguishing the track data of different radars.At the same time,the polar coordinates of the received track data are converted into latitude and longitude coordinates to provide support for subsequent track association,fusion and display.Secondly,in the aspect of data fusion,the independent sequential track association algorithm and convex combination track fusion algorithm which are widely used at present are studied.The two algorithms are implemented by matalb and verified by simulation.Combined with the actual engineering requirements,the three kinds of track states of irrelevant,related and locally related are simulated,and the practicability of the algorithm is proved.Then,the loading method of online electronic map and offline electronic map is introduced.By obtaining the latitude and longitude coordinate information of any position on the online map,the setting,localized storage and visual display of the radar information of each single station in the distributed network radar are realized.At the same time,by loading the offline electronic map and calling the Baidu map API with JavaScript to realize the mapping of the track and the track on the electronic map,the function of displaying and extorting the track data is completed.Finally,this paper uses single-threaded and multi-threaded programming architecture to debug and compare the time efficiency of software running,and determines the important role of multi-threaded software architecture in real-time track display.The distributed radar PC software design studied in this paper has been verified by debugging,and the track data receiving,processing and display accuracy and real-time performance meet the requirements of actual engineering requirements,which has high practicability.
