Q1: Radar Systems - 2024 Real Question
Problem: Calculate the maximum range of a radar system with transmitted power 100 kW, antenna gain 30 dB, and minimum detectable signal -100 dBm.
Solution:
Using radar range equation:
R_max = [Pt × G² × λ² × σ / (4π)³ × S_min]^(1/4)
Where Pt = power, G = gain, λ = wavelength, σ = target cross-section, S_min = minimum signal
(Detailed calculation depends on specific parameters)
