Question 1
What is the Minimum Detectable Signal (Smin)?
- The maximum power of the radar signal.
- The smallest signal power that can be detected.
- The range at which a target can be detected.
💡 Hint: Think of Smin as a threshold for radar detection.
Question 2
True or False: Rmax is independent of environmental factors.
- True
- False
💡 Hint: Consider how common external factors may influence specific radar operations.

Challenge Problems
Push your limits with challenges.
Question 1
A radar system operates at a wavelength of 0.1 m with 1 kW of transmitted power. If the radar cross-section of the target is 2 m², what will be the maximum range if the required Smin is -100 dBm?
💡 Hint: Remember that -100 dBm equals 10^(-100/10) mW, and you’ll need to convert that to Watts.
Question 2
Discuss the implications of a higher noise figure on the radar performance for Smin and Rmax.
💡 Hint: Think about how the noise figure impacts the effectiveness of Smin and what that means for max detection range.
