Furuno Introduces New Digiscan Radars

—Literature Available Furuno announces a new family of modest cost, high performance radars that combine the most advanced technical features with traditional Furuno quality and reliability.

The Furuno FR-800D Digiscan radars have a high brightness, steady picture 12 inch CRT: range scales from % to 36, 48 or 72 nautical miles; output power to 10 kw; antenna lengths from 3 to 8 feet; plus a whole variety of standard built-ins like variable pulselength and PRF's, sea and rain clutter controls, interference rejector, target plot with six selectable intervals, dual variable range markers, dual electronic bearing lines, adjustable sector and range guard zone with alarm, universal 10.2-40 VDC power supply.

Furuno's custom hybrid microwave IC circuitry lets the equipment perform like other radars needing twice the output power, while reducing routine maintenance requirements.

The Digiscan advantage is the way signal processing is done.

Most existing digital, or "rasterscan," radars use single-level quantization.

That is, the returning echo is either present or not present, either "on" or "off". Where the tar- get is weak, or there is heavy precipitation or high seas, there's a chance that important targets may not quite reach a level that is recognized as "present" on the radar. Even seemingly solid targets like a harbor entrance through a breakwater cannot be seen because of "holes" on the screen caused by the system not being sure of whether or not a target is there.

Furuno's Digiscan system recognizes several levels of target return— weak, medium, strong—even in heavy weather. This produces an exceptionally clear radar presentation with all the brightness and picture steadiness one could want.
