Challenge Problems
Push your limits with challenges.
Question 1
A radar system transmits with 500 kW power, has an antenna gain of 40 dB, a radar cross-section of 10 m², and a minimum detectable signal of -100 dBm. Calculate the maximum distance at which a target can be detected.
💡 Hint: Make sure all units are consistent, convert dB to linear before calculation.
Question 2
If a target’s radar cross-section changes due to its orientation relative to the radar, how would this change the detection capabilities of the radar system?
💡 Hint: Think about how shapes reflect sound or light more effectively at certain angles.
