1 Introduction
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
electron tubes) system.
This equipment comprises radar as defined in the Wireless Telegraph

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
