Function
The JMA-2243/2344 series radar devices are marine radar devices that use scanner units
including transmitter and receiver and 10 inch monochrome cathode-ray tube utilizing the
compact raster scan method for achieving a fully semi-conductor adopted (excluding special
electron tubes) system.
This equipment comprises radar as defined in the Wireless Telegraphy Act.

Features
Enhanced fundamental performance of the radar
Through switching among 4 steps in terms of pulse width/cycle switching of frequency and
switching among 3 steps in receiver bandwidth, enhanced fundamental performance of the
radar has been achieved towards display of clearer and higher quality images. Moreover,
through the incorporation of advanced digital signal processing, performance in target de-
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 location of the ship (nu-
merical value) or a mark on the waypoint may be displayed on the screen and through this,
the difference between the bearing of the waypoint and the ship's heading may be grasped
at a glance.
High operability
EBL and VRM that are frequently used are equipped with dedicated switches. Moreover,
4 soft key switches have been incorporated and functions that are relatively frequently used
may be operated with ease. Additionally, a system for selecting functions that are infre-
quently used from the menu has been adopted.
