Introduction
Chapter 3: Standard Radar Operations
3.1 Introduction
This chapter provides detailed instructions for the standard radar operations of
your
hsb
2
series Pathfinder Radar. Additional functions, that are available on
integrated systems with appropriate data sources, are described in Chapter 4.
If you have a combined radar/chart display refer to Chapter 5 and Chapter 6
for information on charting operations.
You can use this chapter with the radar display set to simulator mode, or on the
water after you have installed and set up your
hsb
2
series Pathfinder Plus Radar
system.
This chapter covers the following topics:
• Range control.
• Interpreting and adjusting the radar picture, including adjusting the gain,
sea clutter and rain clutter, changing the targets display, and tuning the
radar.
• Measuring range (distances) and bearings using Variable Range Markers
(VRMs) and Electronic Bearing Lines (EBLs).
• Setting up guard zones and handling alarms.
• Using MARPA for target tracking and risk analysis.
Note: Until you are familiar with interpreting the radar display, you should
take every opportunity to compare the radar’s display patterns with visual
targets, such as other vessels, buoys and coastal structures. You should prac-
tice harbour and coastal navigation during daylight and in clear weather con-
ditions.
If you have a combined radar/chartplotter, or have an
hsb
2
series Chartplotter
as part of an integrated system, you can identify objects using the cursor echo
feature: With cursor echo on (see Section 4.5 and Chapter 7) you can select an
object on the radar display, the cursor is repeated on the chart display so you
can check the object’s identity.
