    1.1 FunctionThe JMA-2243/2344 series radar devices are marine radar devices th

    including transmitter and receiver and 10 inch monochrome cathode-r

    compact raster scan method for achieving a fully semi-conductor adopt

    This equipment comprises radar as defined in the Wireless Telegraph

    1.2 FeaturesEnhanced fundamental performance of the radar

    Through switching among 4 steps in terms of pulse width/cycle switch

    switching among 3 steps in receiver bandwidth, enhanced fundamenta

    radar has been achieved towards display of clearer and higher quality

    through the incorporation of advanced digital signal processing, perfo

    tection during increment weather has been improved.

    Confirmation of the ship's position and identifying the waypoint at a glance

    Through connecting to navigation equipment such as GPS, the loca

    merical value) or a mark on the waypoint may be displayed on the screthe difference between the bearing of the waypoint and the ship's hea

    at a glance.
