Challenge Problems
Push your limits with challenges.
Question 1
If a radar's σ is increased to 20 m² while all other parameters remain constant, how would that affect Rmax?
💡 Hint: Utilize the Rmax equation to see how σ interacts with other parameters.
Question 2
Given a scenario where temperature increases, affecting thermal noise, predict and calculate how this might impact Smin and hence Rmax.
💡 Hint: Understand the relationship between temperature and noise levels.
