Furuno 1932 MARK-2 manual Suppressing Radar Interference, Fixed time trail, Continuous trail

Page 23

Fixed time trail

1.When the elapsed time clock counts up to the trail time selected, the elapsed time display freezes.

2.The oldest portions of trails are erased so only the latest trail, equal in length to the trail time selected, is shown.

3.Trail continues.

For example, the one minute trail time is se- lected. When the elapsed time clock counts up to 60 seconds, the elapsed time display freezes at “60,” but the latest one minute of trail are erased and then trail continuous.

3.5Suppressing Radar Interference

Radar interference may occur when near an- other shipborne radar operating in the same frequency band as your radar. Its on-screen appearance is many bright dots either scat- tered at random or in the form of dotted lines extending from the center to the edge of the display. Figure 3-5 illustrates interference in the form of curved spokes. Interference ef- fects are distinguishable from normal echoes because they do not appear in the same place on successive rotations of the scanner.

Continuous trail

The maximum continuous trail time is 99 min- utes and 59 seconds. When the elapsed time clock counts up to that time the elapsed time display is reset to zero and trail begins again.

Cancelling echo trail

Select “OFF (deactivate)” at “ECHO TRAIL” on the menu.

Changing trail attributes

Trail gradation and trail time can be selected on the OTHERS menu.

Additionally, the unit incorporates adjustable gain and clutter control, giving operators the ability to fine-tune the radar image to suit varying conditions, whether in busy harbors or open waters.

The 1932 MARK-2 utilizes a powerful 2.2 kW magnetron, allowing for excellent range performance. It can effectively detect targets up to 36 nautical miles away, providing mariners with ample warning of potential hazards. This long-range capability is complemented by advanced target tracking technologies, including ARPA (Automatic Radar Plotting Aid). This system enables users to monitor and track multiple vessels simultaneously, providing essential information such as course, speed, and distance for better situational awareness.

In terms of technology, the Furuno 1932 MARK-2 includes a Fast Target Update feature. This allows for rapid refresh rates, ensuring that moving targets are accurately displayed, even in heavy traffic areas. The unit also employs advanced digital signal processing to filter out noise and improve target detection, enhancing overall operational efficiency.

Another key characteristic of the 1932 MARK-2 is its robust build quality. Designed to withstand the marine environment, the unit features a waterproof casing with an IP55 rating, ensuring durability against splashes and humidity. Furthermore, its compact design offers versatile mounting options, making it adaptable for various vessel configurations.

Overall, the Furuno 1932 MARK-2 radar system stands out for its blend of advanced technology, user-centric features, and rugged reliability. Its ability to provide clear and accurate radar imagery makes it an invaluable asset for navigators, enhancing safety and efficiency on the water. As an investment in maritime technology, it offers significant advantages to enhance both recreational and commercial navigation.
