What is the Pulse Repetition Frequency (PRF)? |
Card: 1 / 20 |
|
|
The number of pulses transmitted per unit time. |
Card: 2 / 20 |
|
|
Fill in the blank: The time difference between two successive pulses is called ______. |
Card: 3 / 20 |
|
|
Pulse Repetition Time (PRT) |
Card: 4 / 20 |
|
|
True or False: The Maximum Unambiguous Range (MUR) is calculated using the formula MUR = PRT/12.2 miles. |
Card: 5 / 20 |
|
|
True. |
Card: 6 / 20 |
|
|
Riddle: I am determined by the time it takes for echoes to return, affecting how far you can see. What am I? |
Card: 7 / 20 |
|
|
Pulse Repetition Time (PRT) |
Card: 8 / 20 |
|
|
What is the relationship between the maximum range of a radar system and the transmitted power? |
Card: 9 / 20 |
|
|
Rmax ∝ Pₜ¹/⁴; increasing Pₜ by 16 times doubles Rmax. |

Card: 11 / 20 |
|
|
Σ (Radar cross-section) |
Card: 12 / 20 |
|
|
True or False: Increasing the antenna aperture does not affect the radar range. |
Card: 13 / 20 |
|
|
False. Increasing the antenna aperture improves the radar range. |

What is the formula for Doppler frequency shift (fd) in radar technology? |
Card: 17 / 20 |
|
|
