Design And Implement Of Radar Data Analysis System

Radar data processing is the most important part of the air traffic control system. With the development of multiple radar data fusion, radar data analysis is absolutely necessarily and has a great prospect. This thesis is focused on radar performance analysis and radar data fusion. It is developing an accurate coordinate transformation------WGS-84 coordinate transformation. This article analysis the character of radar data which carries out format examination, protective filtering, and examination repeated SSR code. This article used a method of altitude correction to deal with the mutation of the height. With the idea of object-oriented programming, the article combining radar data format analysis, error analysis, storage, query, display and track comparison of before and after filtration into a system.This article designs one of radar data analysis system by C++ language, which functions are radar data import, analysis, storage, query and quality assessment. After importing the radar data, the system will automatically analysis radar data format, coordinate transformation and extract the useful data. When the length and the format of the radar data are abnormal, the system will show error data message in the window after filtering it. Radar data storage and query is an interconnected operation of MFC and the database. According to the flight number and height, users can inquire some fields'information which is benefit in data processing.Simulation is doing under Windows environment, it proved that this design implement abnormal data filter, normal data showing, fight path showing, data query and some basic functions of radar data analysis. This system's interface is friendly, performance is steady, and have a good practical value.
