Question 1

This suppresses RF leakage when transmitter fires

Answer 1

Main bang suppression

Question 2

Reduces gain of amplifier stage when extremely strong returns are received

Answer 2

Instantaneous automatic gain control (IAGC)

Question 3

Reduces gain to prevent strong echoes of NEAR targets from overwhelming returns of FAR targets

Answer 3

Sensitivity Time Control (STC)

Question 4

Used to differentiate returns from multiple targets by passing only leading edge of echo to the receiver

Answer 4

Fast time constant (FTC)

Question 5

Reduction of wave, reduces range for target detection

Answer 5

Attenuation

Question 6

This is the heart of the indicator

Answer 6

Cathode ray tube

Answer 8

Sweep

Question 9

Frequency, peak power, and antenna rotation rate are all factors affecting what

Answer 9

Maximum range

Question 10

Calibration, ranging scale, radar scope interpretation are all factors affecting what

Answer 10

Range accuracy

Question 11

Two targets on the same bearing cannot be distinguished as separate return unless separated by distance of 1/2 pulse length

Answer 11

Pulse Length

Question 12

Two targets may appear as single return if gain is too high

Answer 12

Receiver gain
