Collection And Processing Of Lfmcw Radar

Based on the relevant research of the LFMCW radar signal processing arithmetic, the data acquisition theory and the arithmetic realization by the digital signal processor (DSP) chip's, this dissertation take charge the data acquisition and singal processing system of one LFMCW radar. As an important part of the radar system, this work contains the project design, the development of hardware, the software realization and the debugging of system. The main research work and results can be summarized as follows: 1. Accomplished the analog data acqisition and processing system project design of analog quadrature receiver of a LFMCW radar based on the LFMCW signal detection theory as the requriment of the whole system; 2. Accomplished the data acquisition board principle circuit design and tested the board performance; 3. Using the Hammerhead PC/104-Plus board based on two ADSP-21160 DSPs as the hardware platform, this paper realized the medium temporal logic of the whole data processing blockettes and accomplished the program loading and debugging. 4. Accomplished the I/O hardware and software design, realize the data transmission between the boards successfully. 5. Debug with the other parts of the whole receivers. The research results indicate that the signal processing system is coincident with the radar system's demand in function. And the main parameters gained by test reach the radar system's design demand.
