[Abstract]:At present, the speed measuring equipment is changing with each passing day, and the real-time processing system of the speed measuring radar has made great progress as one of the core equipments of the velocity measurement system. The research and development of real-time processing system is of great strategic significance for the upgrading of speed measuring equipment in our country. In recent years, with the rapid development of arm embedded system, a large number of high-performance applications have been produced. At the same time, the performance and price ratio of FPGA has been improved constantly, which makes the application based on FPGA more and more extensive. Aiming at the problems of poor real-time performance, high power consumption and high price in the real-time signal processing system of speed measuring equipment, this paper proposes a scheme combining ARM11 embedded technology with FPGA digital signal processing technology. This scheme takes ARM11 as the core, FPGA as the signal processing chip and the software operating system as embedded Linux operating system. The main work of this thesis is as follows: the design and implementation of the hardware circuit of the system, the FPGA implementation of real-time digital signal processing, the design and development of the interface driver of embedded Linux transplanting ARM11 and FPGA, the design of power spectrum analysis application program. QT platform application program design; system test results error analysis. Through the repeated debugging and continuous improvement of each module and system, a real-time processing system of speed measuring radar with satisfactory performance and various parameters is successfully completed.
