.5 Mm Band Fmcw Radar System And Signal Analysis

Based on precondition of the tentative research of 5mm millimeter wave radar, this thesis analyses, in 5mm wave band, the characters of difference signals, receiver, matching filter and ambiguity function in FMCW system.Firstly, this thesis introduces correlative information, such as radar theory, modulation, matching filter, ambiguity function, in the domain of processing of radar signals. Based on this, this thesis analyses difference signals in FMCW system, and the performance of Difference-Fourier receiver. Afterwards, it advances a method of matching filter, and analyses ambiguity function of radar in order to researches the system of FMCW radar. Then, it advances a new method of parameter analysis, which utilizes known parameters to make modeling based on physics meaning or distributing graph of parameters. This method, which utilizes LMS arithmetic, is first advanced in the domain of processing of radar signals, so it is only an attempt. If it can be used in practice. I will lucubrate the method in the future.In chapter five, this thesis provides a method of manufacture of power supply of radar. It analyses this kind of power supply, and finished products are produced practically. After producing the power supplies, the correlative parameters are testedFinally, this thesis introduces DSP of TI, and FFT simulation is done, using CCS, based on the known parameters. The results illuminate that realization, using DSP, is feasible. This make ready for the hardware circuit, which is realized by DSP.
