| As a very important environment and weather detecting tool, weather radar hasbeen attached very importance by many countries of the world. Applications ofweather radar have been widely extended from meteorology to important departmentsof national economy such as military affairs, bussiness, environment, agriculture andforestry, navigation, and traffic etc.Therefore, developing and researching advancedweather radar and improving their detecting capability are important task for theworld.This thesis introduces the applications,developing course and direction ofweather radar in detailed. Analysing and expounding the research actualities ofdual-linear polarization weather radar in the last decade and tell us the developingspace and direction of the field.Presenting theory of weather radar includingScattering of electromagnetic wave on weather particles, weather radar formula ,andecho signal processing principle of NEXRAD in theoretics. The author have donemany reading and summarization to analysis relative materials and expounded theoryand application of dual-linear polarization weather Doppler radar systemically.Having compared with most advanced dual-linear polarization weather Doppler radarsystems in their structures and different running modes. Introducing the differencebetween two modes and their developing directions. Presenting methods of estimatingpolarization parameters . This chapter gives a deeply and completely introduce ofdual-linear polarization weather Doppler radar system in this fields.A dual-linear polarization weather Doppler radar signal processing system baseson TMS320C6701 DSP is designed , as foundations author presents TMS320C6701high speed DSPs , the implement platform TMS320C6701 Evaluation ModuleEVM6701,EMIF interface and DSPLINK2 interface in detailed and based on the twointerfaces the anthor design a interface circuits board to complete the signalprocessing system design.All routines are coded in MATLAB. we can get weather echo, Doppler... |
