| Abstract: | In terms of the characteristics of the FFT beam former of imaging sonar,the FFT beam former is designed by FPGA.The whole system is built by DSP Builder of Altera.The FFT beam former uses 512 points DIT-FFT radix 2 algorithm,pipeline technology and Ping-Pong operation.The system is tested in the hardware of Altera StratixII EP2S90F784I4.The system can gain the FFT results of 512 points in 17.07 μs under the condition of system clock 30 MHz,which can meet the requirement of the beam former of imaging sonar easily. |
