(B)Element 8-13 Modulation Flashcards
1
Q
In a solid state RADAR modulator, the duration of the transmitted pulse is determined by:
A
the pulse forming network
2
Q
The modulation frequency of most RADAR systems is between:
A
60 and 500 Hz
3
Q
A shipboard RADAR uses a PFN driving a magnetron cathode through a step–up transformer. this results in which type of modulation?
A
pulse modulation
4
Q
In a pulse magnetron what device determined the shape and width of the pulse?
A
Pulse forming network
5
Q
What devices may act as the modulator of a RADAR system?
A
Thyratron or a silicon controlled rectifier SCR
6
Q
The purpose of a modulator in the transmitter section of a RADAR is to:
A
provide the correct waveform to the transmitter
7
Q
