| Based on the researching signal processing theory and methods of LFMCW radar, this thesis investigates the principle methods and related issues of LFMCW radar gun under the dual-beam. Design hardware and software of signal processing of LFMCW radar. The main works are as following:(1) Signal processing methods for the detection of LFMCW radar are researched. Focusing on accessing speed, models and other information from the echo, and schemes of gun under the signal-beam and dual-beam, The feasibility of the schemes are discussed, and the speed measurement errors are analyzed, The scheme of dual-beam is determined.(2) Signal processing hardware is composed of TMS320C6713, AD9220 and EPM7128 ,The design process of data acquisition and signal processing module are introduced in detail, including the selection device, the design of EMIF interface, conversion and PCB-level. Signal processing hardware is alignment. The task of developing the signal processor is completed.(3)Signal processing software is designed, including the loading procedure, the design of interface parameters and algorithm programming. The speed of the algorithm is optimized. Commissioning results show that meet the requirement... |
