ABSTRACTLinear ABSTRACT Linear frequency modulated continuous wave(LFMCW)radar has many characteristics of simple structure，small volume，light weight,low cost,low transmitter peak power，short wavelength，thus it is especially suitable to be used in radar image，research oftarget characteristic,end control and guide，battlefield spy, scene watch etc．and more people in the world interested in it。it will have a wide prospect．In present,Olaf country had many achievements in research in linear frequency modulated continuous radar,but if we want to turn those achievements into practicality application，it need one efficiency hardware platform．In this dissertation，one general digital signal processing hardware platform WaS established which based in progress in DSP technology and inter cimuit technology, In this dissertation，at first，introducing the theory of linear frequency modulated continuous wave radar．The designing ofthe signal processing hardware platform is basing on the algorithm．The collecting data can be inputted through dual-port RAM，also caP．be inputted though PCI imefface． Briefly,here are main topics ofthis dissertation： (1)The relation between the resolving power ofthe linear frequency modulated continuous wage radar and the linearity of linear frequency modulation signal． (2)Introducing DSP technology and PCI interface technology．TMS320C6201 was a kind of new and hi馥鲫DSE Its the core device of the genera／ digital signal processing hardware platform．PLX9054 is a general PCI controller,it has the property ofhigh performance and friendly interface．In the dissertation,introduced the main characteristic of TMS320C6201。and finishedthe schematic design． (3)PCB routing and the signal integrality simulator were completed． H (4)The (4)The program of FFT algorithm was completed in C．It was an evaluating for the general digital signal processing hardware platform． Key Words：Linear Frequency Modulated Continuous Wave Radar,DSP,PCI． Signal integrality,SDRAM III 独创性声明本人声明所里
