The Design And Study Of Radar Complicated Waveforms

The work in the paper firstly studies some theories of Radar signal, mainly the Barker sequences and m-sequences: (1) the advantage and the disadvantage of the Barker sequences and the theory of complementerry combined Barker sequences ;(2) the advantage and the disadvantage of m-sequences;(3) the dopller infection of frequency shift for their pluse compress.On the basis of the study for the radar signal theory, further study the radar-complicated waveforms. Basing on the design of PCP (Programmable Coded Pluse) module, some waveform transform circuit Throuthing the microprocessor controlling the coded-pulse wave with random combination to export. The coded-pulse wave, also, throuthing waveform transform circuit, programming codes to control the switch to choose capacitance of the integral circuit, exporting sine and non-sine the radar complicated waveforms.With the development of MicroSystem chip SOC and the technology of EDA (Electronic Design Automation ), PCP module and waveform transform circuit can be realized by employing MicroSystem chip SOC. The design of radar-complicated waveforms can be realized on the MicroSystem chip SOC.
