| Abstract: |
| A target simulator has great significance in development and produc
tion process of radar, for it can not only speed up the progress of the projec
t development,but also reduce the cost of research and experiment.The simul
ator descriked in this paper is mainly designed for pulse-compress radars.Throu
gh radar echo IF signal simulation, the simulator is achieved by FPGA t
echnology,which is featured by simple design,conveniency,low cost,etc.In this p
aper,firstly,according to system requirements,a mathematical model of the two-p
hase code PC radar target echo signal is established,and radar
antenna scan-status is simulated by using SINC function；then,the design solution based on FPGA and the implementation method of the main module are given; finally,the conclusion that the design is feasible is given,at the same time,the improvements in the future are pointed out. |
