To meet the high precision of the doppler velocity measuring sonar, the broad band transmitting signal and phased- array are used, also with the high speed, parallel, real-time characteristic of processing data by FPGAs, the digital system of the Doppler velocity measuring sonar is designed and implemented on the core of Ahera＇s StratixII EP2S60F48414 FPGA , the sampling control, band-pass filtering, beam forming, correIation operation and other signal processing algorithms have been realized . Mean- while, the test results show that the broad band signal can meet the high precision of sonar system better.
