Research On Data Preprocessing System Of Flight Test Based On Matlab GUI

With the increasingly serious problem of air pollution,people's requirements for the monitoring accuracy of aerosol and PM2.5 of air pollutants are also increasing.The traditional monitoring method is to calculate the content of PM2.5 by building a monitoring station on the ground.This method not only consumes a lot of manpower and material resources,but also cannot meet the requirements in accuracy.The most important thing is that this method also has regional limitations,which can not be monitored in the area without monitoring stations.With the rapid development of satellite remote sensing technology,it is gradually developing from ground monitoring to satellite remote sensing monitoring.The remote sensing data of air flight is huge and the parameters are very professional.The data of each test needs to be analyzed and processed again,which aggravates the workload of later stage.Therefore,a software which can preprocess the test data is needed.After analyzing the flight test data,based on the powerful computing ability of MATLAB,the system transforms and preprocesses the POSP data and the simultaneous polarization camera data collected by the ground inspection system of the self-developed software,Development of data processing software for flight test based on GUI design function of MATLAB.Through this software,the calibration coefficients of POSP and simultaneous polarization camera can be obtained,and the polarization correction can be completed.The result of this processing is to provide input for the inversion of atmospheric characteristics,so as to measure and calculate the content of PM2.5.This processing system has passed many tests and met the software requirements.All functions of test data processing can achieve the expected results.It lays a foundation for the product development in the later stage of flight test,greatly reduces the workload of data processing,and provides an important reference value for later data processing.
