Tracking Radar U-4 Quiz

What is the primary function of tracking radar?

• To analyze the target's size

• To measure the speed of the target

• To continuously maintain the antenna beam on the target

• To detect the presence of targets

Which method is NOT used to generate the error signal in tracking radar?

• Phase comparison

• Conical scan

• Frequency modulation

• Sequential lobing

What is the purpose of the servomechanism in continuous tracking radar?

• To amplify the echo signal

• To position the antenna beam

• To filter noise from the signal

• To acquire the target

In sequential lobing, how is the angular error determined?

• By using a single antenna beam

• By switching the antenna beam between two positions

• By comparing the amplitude of signals

• By measuring the phase difference

What is the main advantage of conical scan over sequential lobing?

• Higher accuracy

• Lower cost

• Less complexity

• Continuous tracking

Which component is essential for automatic gain control (AGC) in tracking radar?

• A phase-sensitive detector

• A boxcar generator

• A low-pass filter

• A servo motor

What is the primary disadvantage of conical-scan and sequential-lobing tracking radars?

• They are too expensive

• They cannot track fast-moving targets

• They are too complex to operate

• They require multiple pulses to extract the angle-error signal

In monopulse tracking radar, how is angle-error information obtained?

• By comparing the phase of signals from two antennas

• By measuring the amplitude of echo signals

• By using a single antenna beam

• By using multiple pulses

What is the function of the boxcar generator in tracking radar?

• To amplify the echo signal

• To control the antenna position

• To stretch the pulses before filtering

• To generate the error signal

What is the purpose of the split range gate in tracking radar?

• To track the target in range

• To filter noise from the signal

• To enhance the echo signal

• To isolate multiple targets
