Chapter 1 Introduction
1.1 Functions
This device is a marine radar device that utilizes a scanner unit including transmitter and
receiver and 10.4 inch liquid crystal display unit and uses a compact raster scan method for
achieving a fully semiconductor adopted (except for special electron tubes) system.
This equipment comprises radar as defined in the Wireless Telegraphy Act.
1.2 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 high 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 external navigation equipment such as GPS, the location of the ship
(numerical values) or a mark on the waypoint may be displayed on the screen. This allows for
confirmation of the difference between the waypoint and the ship's heading at a glance.
High operability
A jog dial has been incorporated for simple operation of menu selections, EBL/VRM.
The track ball may also be used to capture the MARPA target in a simple manner.
A system for the direct display of menu items that are frequently used with dedicated keys has
been adopted.
