Chapter 2 - Radar Transmitters

Question 1

label generic radar transmitter and pulse trains

Answer 1

Question 2

Label typical radar pulse train leaving oscillator

Answer 2

Question 3

Draw typical radar pulse in freq domain

Answer 3

Question 4

Why would you use a long pulse duration in radar?

Answer 4

o Increased Range: A longer pulse duration increases the average power, extending the radar’s detection range.
o Improved Detection: Enhances the ability to detect weak targets by increasing the signal energy.

Question 5

What effect does a short pulse have on range res and min range

Answer 5

Higher range resolution and shorter minimum ranges

Question 6

Explain operation of magnetron in bullet points

Answer 6

Cathodes emits electrons that want to go to anode
large magnet bends electron stream to resonant cavities
as electrons pass through cavities they start to oscillate
oscillation freq is determined by inductance and capacitance of cavities
combines oscillations produce narrowband RF

Question 7

What is the MUR, Rres, Pav equations

Answer 7

MUR = cT/2

Rres = ct/2

Pav = Ppk x t x PRF
