FACTORS WHICH MIGHT RESULT TO FAULTY INTERPRETATION OF RADAR DIS

What is the primary function of a Plan Position Indicator (PPI)?

• To provide a two-dimensional display of radar data

• To calculate the altitude of flying objects

• To generate weather maps for meteorologists

• To display satellite images

How does the PPI display detected objects in terms of their position relative to the radar station?

• It shows their altitude and speed

• It plots their range and bearing

• It calculates their size and weight

• It only displays objects moving toward the radar

Which feature of the PPI helps in determining the precise distance to a specific target?

• Range Rings

• Electronic Bearing Lines (EBLs)

• Variable Range Markers (VRMs)

• Clutter Suppression

Which key feature of the PPI would be most useful for avoiding collisions in real-time?

• True Motion Display

• Range Rings

• Clutter Suppression

• Bearing Lines

In which situation would clutter suppression on a PPI be most useful?

• Navigating through a busy shipping lane

• Reducing interference from sea or rain clutter

• Enhancing the detection of aircraft

• Calculating the speed of fast-moving targets

Which feature of the PPI displays the past positions of moving targets?

• Zoom and Range Scaling

• Target Trails

• Relative Motion Display

• Range Rings

How do Electronic Bearing Lines (EBLs) aid radar operators using the PPI?

• By filtering out false echoes

• By measuring the distance to the horizon

• By measuring the direction of targets

• By magnifying the radar display

Which factor can lead to faulty interpretation due to ship obstructions such as masts or cranes?

• Beamwidth distortion

• Target Smearing

• Blind Sectors and Shadowing

• Clutter Suppression

What could happen if the radar's gain is set too high on a PPI display?

• Targets may appear smeared

• False echoes may obscure real targets

• Distant targets may not appear

• The radar may fail to detect moving objects

Which issue occurs due to the radar beam's width distorting the true size and position of targets?

• Parallax Error

• Radar Horizon Limitations

• Beamwidth Distortion

• Target Smearing
