The Design & Implementation Of Data Receiving And Processing System For High Resolution Remote Sensing Image

In the field of aerospace measurement,information exchange exists in everywhere.Large data transfer and handling is more and more important whether in payload management or ground-test.As mature technique of network,the application of net in aerospace ground-test has became one of development directions.In addition,with the remote sensing load become more complex,aerospace ground-test must be more strict,accurate and high-efficiency.It is a trend that using net to improve efficiency of ground-test.Therefore,the research of this topic is prospective,which can be used for other projects.This mainly content of this paper is receiving and processing of high-resolution remote sensing image based on TCP/IP.The purpose of this project is to reform the ground equipment used for remote sensing camera ground-test to adapt requirement of satellite ground-test.Firstly,this paper introduces the background of the project.It puts forward the first important problem in the project,that high-speed transmission of large data.According to requirement of satellite ground-test,the paper introduces some functional and non-functional requirements.The general scheme of "saving firstly" is put forward to resolve the problem of large data and high transmission rate.Moreover,this paper introduced core technology of software,like multithread processing,DLL,memory map and interlocking technology,to resolve the problem of high-speed transmission of large data.The core technology makes the software more reliable.It described the function framework of software in the scheme.It also introduced the MTF model,the SNR model and the model of no-uniformity correction in detail.According to function framework of software,it introduces the scheme of each functional module in detailed design.The functional and non functional testing is introduced in the last chapter.The reliability of the various technical measures applied to the software system,and the accuracy of the functionality is verified by functional and non functional testing.
