Features
The new FR-2805 series of radar and the FAR-2805 series of ARPAs are the results of com-
bination of the FURUNO's many years of experience in the marine field and the advanced
computer technology. The FR-2805 series and FAR-2805 series are designed to fully meet
the exacting rules of the International Maritime Organization (IMO) for installations on all classes
of vessels.
The display unit employs a 28" diagonal high-resolution green-phosphor CRT. It provides an
effective radar picture of 360 mm diameter leaving sufficient space for on-screen alphanu-
meric data.
Target detection is enhanced by the sophisticated signal processing technique such as multi-
level quantization (MLQ), echo stretch, echo average, and a built-in radar interference rejec-
tor. Audible and visual guard zone alarms are provided as standard. Other ship's movement is
assessed by trails of target echoes or by electronic plotting. The FAR-2805 series ARPA fur-
ther provides target assessment by historical plots, vectors and target data table.
On-screen data readouts include CPA, TCPA, range, bearing, speed/course of own ship and
up to 3 targets. The ARPA functions include automatic acquisition of up to 20 targets, or
manual acquisition of 40 targets. In addition, the ARPA features display of a traffic lane, buoys,
dangerous points, and other important reference points.
