synchronous operation and are related to PRF? -Correct Answer ✔Synchronizer (timer)
What part of radar system contains a pulse forming network (PFN) that produces high
volt pulse to fire transmitter? -Correct Answer ✔Modulator
What fires the transmitter? -Correct Answer ✔Pulse Forming Network
What part of radar system produces electromagnetic energy in the form of continuous
waves or short powerful pulses? -Correct Answer ✔Transmitter
What part of radar system is an RF switch that permits radar system to use a SINGLE
antenna to both receive/transmit? -Correct Answer ✔Duplexer

returns, and shapes signal for clarity? -Correct Answer ✔Video processor
Which part of radar system uses processed video signals to give operator visual
indication of object info? -Correct Answer ✔Display
How is gain of an active device (amp) or loss of a passive device (attenuator)
expressed? -Correct Answer ✔Decibels (dB)
Decibels represent a change in what? -Correct Answer ✔Power level
What is the ability of a radar to distinguish multiple targets from one another when they
are close together? -Correct Answer ✔Resolution
What are two types of radar resolution? -Correct Answer ✔Range and Bearing (angular)
resolution
What plays a large part in quality of range resolution? -Correct Answer ✔Pulse Width
What is the ability of radar to separate objects at the SAME range but at DIFFERENT
bearing or elevation angles? -Correct Answer ✔Bearing (angular) resolution
What is the ability of the radar to determine range, bearing, and height of an object? -
Correct Answer ✔Radar accuracy
What three things affect radar accuracy? -Correct Answer ✔Pulse shape, atmospheric
conditions, and resolution (primary)
What is the bending of RF waves caused by change in density of medium (atmosphere)
it passes through? -Correct Answer ✔Refraction
What causes ducting? -Correct Answer ✔Temp inversion and moisture lapse
What are two types of pulse radar systems? -Correct Answer ✔Search and tracking
radars
What is a variation of pulse modulation? -Correct Answer ✔Pulse doppler
