| Radar signal simulation system has been applied in lots of fields,such as radar system design,radar system analysis and radar function test. Presently,most Radar signal simulation system was realized by the use of PC and programmable VLSI. The system is agile,current and easy to maintain.The task of this project is to design a hardware platform for radar video simulation and calculate the pulse-compression video signal of linear frequency modulation (LFM) radar system.In this paper,the relative acknowledge of radar signal simulation system is introduced briefly,at first. Then,a general platform is given which is referred to the software radio principle and made up with DSP and FPGA.The fixed-point DSP program is given which are based on the analysis in thefeather of the video signal and the 16-bit fixed-point DSP--TMS320C5402. At last,the result and quantity of calculation are analyzed to prove that the speed and precision of calculation are matched to the system requirement. |
