| description | The invention relates to a wide-band signal processing system and method for acoustic Doppler current section apparatus, including an acoustic Doppler current section apparatus module, a signal processing mainboard plus a data collecting card, a computer system and cables, where the acoustic Doppler current section apparatus module inputs the received wide-band analog sound signal into the data collecting card by the cables, the data collecting card collects the analog sound signal and directly sends the collected data to the signal processing mainboard for processing, and the computer system operates the whole course and displays the results by pictures. Its advantages: for increasing the accuracy and space resolution of ocean current measurement, it adopts m-sequence code wide-band pulse signals and adopts multiple relative signal processing technique to extract two or many phase differences of same m-sequence code wide-band pulse signals and thus obtaining the moving speed of the apparatus relative to the sea water or seabed, and it has high stability for long working and is not limited by frequency and pulse width. |
