What does the term 'sub clutter visibility' refer to?

• The ability to detect moving targets over clutter

• The clarity of radar images

• The ability to detect stationary targets

• The range of radar signals

What is the role of the phase detector in MTI radar?

• To generate the local oscillator signal

• To produce an output signal from two input signals

• To amplify the received signals

• To filter out unwanted frequencies
