Radar Principles Quiz

In principle of radar, how is the distance to target been determined?

• By measuring the time taken for the radar signal to travel to the target

• By measuring the travel back time taken for the radar signal from the target

• By measuring the time taken for the radar signal to travel to the target and back

By measuring the time taken for radar signal to travel to the target and back.

• the period to target determined

• the wavelength to target determined

• the distance to target determined

What types of radar that the target and radar installation are not cooperate to each other.

• Echo radar

• Primary radar

• Secondary radar

In Primary radar, the target and radar installation are

• not cooperate to each other

• cooperates to each other

• matching to each other

Radar receiver should ignore reflections from fixed objects and respond only to moving target. This can be achieved by using.

• Doppler Effect

• Amplitude object

• Frequency Effect

Radar receiver that can differentiate between fixed objects and moving target can be achieved by using.

• Doppler Effect

• Amplitude object

• Frequency Effect

The term Doppler Effect is meant by.

• Receiver should ignore reflections from moving target objects and respond only to fixed target

• Receiver should ignore reflections from fixed objects and respond only to moving target

• Receiver should ignore reflections from fixed objects and respond only to fixed target
