Developed at the Department of Marine Electronics Systems, Gdansk University of
Technology, the acoustic processor is an element of the MG-89, an underwater acoustic
station. The focus of the article is on the modules of the processor. They are responsible for
sampling analogue signals and implementing the algorithms controlling the measurement
cycle and digital signal processing. As it performs the above functions, the device should be
highly reliable and resistant to mechanical and weather conditions and ensure a user friendly
operation. The functions of the processor software should help with object detection and
classification. The results of measurements should be displayed with the shortest possible
delay in relation to sounding signals to allow the operator to take decisions quickly and
establish if the object poses a risk. The article demonstrates that the acoustic processor
designed for and used by the Navy meets these requirements.
