Research On Technology Of Broadband Complicated Radar Signal Synthesis

Nowadays，Wideband radar is widely used in the military, civil, commercial andmany other fields with its various characteristics. Such as through-the-wall radar, radiobase station, electronic reconnaissance, target location etc. It is widely concerned bymany country, because of its high resolution, strong target recognition ability, stronganti-interference ability etc. So, it is important to have study on synthesis of widebandradar signal and improve the performance of wideband radar.This paper dose research on three methods on wideband or ultra wideband signalsynthesis. Pseudo random sequence signal synthesis technology based on high speedserial port module of Xilinx series FPGA, the digital rate of the signal can be up to afew Gigabit; the method of wideband radar signal synthesis based on the multiple phasechannelized can make multiple channels of signal to a wideband signal; the multichannels wideband radar signal synthesis technique based on multiphase structure, cangenerate multi channels signal, signal of each channel can have many modulation, suchas LFM, BPSK and so on, phase difference between channels in normal mode iscontrollable. This paper dose deep research on the various technologies and proposesthe algorithm and framework of various wideband complicated radar signal synthesistechnology. Finally, this paper validates the function of the several kinds of methods bymeans of Matlab simulation or debugging based on printed circuit board, and proves thefeasibility of various waveform synthesis technology.
