PADS 50kHz



              OPG has been developing multi-beam phased array doppler sonars (PADS) for use in examining sea surface current structures since the mid 1990's. Early devices operated in the 200 kHz band with maximum ranges between 250 and 500 m. In 2002, OPG developed a 16 beam 50kHz PADS system, in order to be able to image the sea surface at ranges of 1.5 km or greater at a resolution where internal wave signals could be resolved.
