◉ What are 9 parts of a basic radar system?
Answer: Modulator, synchronizer, antenna, antenna control,
transmitter, receiver, display, video processor, duplexer
◉ What part of a radar system controls all radar system timing
signals that ensure synchronous operation and are related to PRF?
Answer: Synchronizer (timer)
◉ What part of radar system contains a pulse forming network
(PFN) that produces high volt pulse to fire transmitter?
Answer: Modulator
◉ What fires the transmitter?
Answer: Pulse Forming Network
◉ What part of radar system produces electromagnetic energy in
the form of continuous waves or short powerful pulses?
Answer: Transmitter
,◉ What part of radar system is an RF switch that permits radar
system to use a SINGLE antenna to both receive/transmit?
Answer: Duplexer
◉ What part of radar system focuses transmitted EM energy into a
beam, radiates it out into space, and catches the echo signal?
Answer: Antenna
◉ Which part of radar system consists of electromechanical devices
such as synchros, servos, and gyros that correctly position antenna?
Answer: Antenna control
◉ Which part of radar system amplifies and concerts returned RF
echo into video signal?
Answer: Receiver
◉ Which part of radar system analyzes video signal from receiver,
detects inconsistent returns, and shapes signal for clarity?
Answer: Video processor
◉ Which part of radar system uses processed video signals to give
operator visual indication of object info?
, Answer: Display
◉ How is gain of an active device (amp) or loss of a passive device
(attenuator) expressed?
Answer: Decibels (dB)
◉ Decibels represent a change in what?
Answer: Power level
◉ What is the ability of a radar to distinguish multiple targets from
one another when they are close together?
Answer: Resolution
◉ What are two types of radar resolution?
Answer: Range and Bearing (angular) resolution
◉ What plays a large part in quality of range resolution?
Answer: Pulse Width
◉ What is the ability of radar to separate objects at the SAME range
but at DIFFERENT bearing or elevation angles?
Answer: Bearing (angular) resolution
