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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
