Reseach On Long Distance Radar Data Fusion

This paper focuses on the long-distance detection radar, analyzes the limitation ofthe single-station model. In the light of the false track difficult identification and thedistal track difficult initiation problems, we propose a method to improve theperformance by using double station mode and specific project implementation. Themain contents are the following sections:(1) The special problems of long distance detection radar double station system arethe non synchronization of the data from different stations, and not matching in space.Since the data processing cycle of different stations varies and transmission networkdelay, data from different stations is in the different time point. If we do data associatingin direct, the large error is brought into the processing. Thus, we can choose A station asthe main station, extrapolating B data to A data time to minimize the error. ThisMatching method is suitable for the real-time system. In space, the data is based ondifferent radar coordinates, so we can transform B data to latitude and longitude first,and then turn them into the coordinate of data A station.(2) Long distance detection radar track fusion project implementation. This partintroduces the composition of the track fusion module and generally gives thedescription of the function and implementation process of each module. Besides, thetrack number management method is given based on hybrid memory allocation, whichimproves the efficiency of program execution. The method of tracking numbersaccording to the characteristics is successfully applied in solving the duplicate numberproblem. Finally, we can test the performance of the program by checking whether theprogram can search on the associated track in very dense area as well as its fusing andmaintaining through experimental data.(3) Long distance detection radar point synthesis realization in project method.Describe the composition of the point synthesis module, show the function and theimplementation of each part. Briefly introduce the adaptive point synthesis algorithm.Propose four ways to prevent the false track initiation, which can promote the rapidinitiation of high-quality track at the same time. By simulation, we can verify thereliability of the point synthesis program, analyze the advantages of the point synthesis,to prove which is better than the single mode. Finally, using the experimental datatesting the program.
