Implementation of coded pulse complex correlation algorithm on broadband ADCP

According to the needs of testing broadband ADCP, it is studied the measurement principle and the coded pulse complex correlation algorithm. Based on the characteristics of the measurement and coded pulse, it is simulated the coded pulse complex correlation algorithm of the broadband ADCP. In this paper, the complex correlation algorithm is simple and convenient. Simulation results show that the algorithm can estimate Doppler frequency in the case of low SNR. The algorithm fully meets the requirements of ADCP Doppler frequency measurement.
