The Design Of Radar Signal Produced By Software And Hardware Based On DDS

With the rapid development of modern electronic techniques,radar techniques are also developing quickly . so more and more different sorts of radar system come into being.Radar chooses different kinds of signal form vary from its system. Especially the creation of the super scale and super speed digital signal process integrated circuit makes the techniques of radar signal process develop rapidly to the digital direction and improves the processing ability of radar signal. The unseen modern electronics and information competition requires that radar system should have the advantage of super discrimination, against-interruption, anti-hiding, low-capture and against-destruction.Therefore, the application of super wide belt radar techniques, pulse compress techniques, digital receive techniques and many techniques based on DSP in radar have become the hot topics in the research of modern radar design and production. The topic of this thesis orginates from a unit of a electronic system and its main duty is that auording to all kinds of common radar wave form which is brought forth according to the given requirement and let the students have a whole picture of the whole system and process of radar signal handling and some common numerical signal processing algorithm. At the same time, it can provide a experimental environment for grasping the most popular and top Dsp system and applied design and development technology of FPGA system and its related development software.At the beginning of this thesis it briefly talks about the basic knowledge of radar signal, especially the basic theory of pulse compressing and the methods of bringing forth linear FM pulse compress signal. It states in detail the choices of scheme and mechanism of hardwave of this experimental board. It also tells the reader the related process design process and sets examples. It comines these two development softwave of quartusⅡand visual DSP++ to introduce the development of FPGA and DSP chips in order to be convenient for the development of experiment board. Finally it briefly introduce the debug content of the experimental board and the items which should be noticed.
