Blackboard HW: RADAR Navigation

The radar operator can adjust the displayed image by altering the following settings:

Amplification of received radar return (Gain), filters to remove clutter (Sea, Rain).

Receiver

Amplifies the weak returning echoes and demodulates them for display.

All of the following are uses of RADAR EXCEPT

Chart Corrections.

Display

Display information and provide access to function.

An ___________ is an electronic means of measuring the radar bearing of an object on the radar screen.

EBL.

Navigation radars typically operate at high frequencies and low pulse lengths. This causes them to have...

High resolution, short range.

Duplexer

Isolates receiver from transmitter while permitting them to share a common antenna.

When is not a situation in which you would use Parallel Indexing?

No identifiable radar land marks.

Transmitter

Produces electromagnetic waves of energy.

A Parallel Index (PI) is used during pilotage to:

Provide continuous assessment of a ship's position relative to the planned track.

Which of the following is not a limitation on radar operation?

Radar only works in two dimensions

Antenna

Transmit outgoing pulses/ receive returning echoes

Shorelines with large tidal ranges can drastically change its image on RADAR between low and high tides.

True.

Which RADAR tool can be used to mark the distance of the drop range while anchoring?

Variable Range Marker.
