What effect does fog typically have on radar signals?

• Reflects signals forward only

• Amplifies the radar return

• Scatters and reduces accuracy

• Enhances surface resolution

Why are large metal targets easier to detect by radar?

• Absorb signal energy well

• Create scattered returns

• Have high reflectivity rate

• Reduce Doppler tracking

What is the role of Moving Target Indication (MTI)?

• Filters color saturation

• Enhances Doppler shifts

• Suppresses moving echoes

• Reduces unwanted clutter

Why is rain clutter problematic on radar screens?

• Fades target intensity

• Mimics radar beacons

• Masks vital targets

• Increases display delay

What happens when radar signals hit snow?

• Signals become clearer

• All targets disappear

• Echoes become unreadable

• Signals get attenuated

If clutter masks small boats near the coast, what control should be used?

• Doppler signal tracking

• MTI clutter reduction

• Manual bearing tuning

• Off-centering display

Which action helps minimize radar blind sectors?

• Use multipath filters

• Raise the signal gain

• Install second antenna

• Set heading to North

When encountering Doppler shifts from targets, what is being detected?

• Target orientation only

• Interference from jamming

• Movement of the targets

• Shape of radar echoes

If sea return dominates the screen near the bow, how do you respond?

• Zoom to full scale mode

• Decrease range rings

• Apply sea clutter filter

• Reboot radar system

When strong echoes from racons obscure nearby vessels, what helps?

• Reduce VRM intensity

• Enable beacon ignore

• Activate EBL masking

• Adjust display filters
