🔹113 TECH FUNDAMENTALS

Question 1

🔹Ducting

Answer 1

Trapping an RF wave between 2 layers of atmosphere

Question 2

🔹PRI

Answer 2

Pulse Repetition Interval

• Duration of time between the point on the pulse to the identical point on the next pulse

Question 3

🔹PRF

Answer 3

Pulse Repetition Frequency

• The rate at which pulses are transmitted, given in hertz or pulses per second.

Reciprocal of Pulse Repetition Tim (PRT)

Question 4

🔹RF

Answer 4

Radio Frequency

• Frequency of the carrier wave which is being modulate to form the pulse train

Question 5

🔹BW

Answer 5

Beam Width

• When the half-power points are connected to the antenna by a curve, the resulting angular width of the curve

Question 6

🔹Pulse width

Answer 6

The duration of the pulse

Question 7

🔹Scan

Answer 7

– Systematic movement of a radar beam to cover a definite pattern or area in space.

The type and method of scanning used depends on the purpose and type of radar and on the antenna size and design

Question 8

🔹What does RADAR stand for?

Answer 8

Radio Detection And Ranging

Question 9

🔹What target information is provided by a 3-D radar versus a 2-D radar?

Answer 9

3-D provides range, azimuth, and elevation

2-D only provides 2 of the 3
