During a test, a nato surveillance radar system, operating at 37 ghz at 182 kw of power, attempts to detect an incoming stealth aircraft at 104 km. assume that the radar beam is emitted uniformly over a hemisphere. (a) what is the intensity of the beam when the beam reaches the aircraft's location? the aircraft reflects radar waves as though it has a cross-sectional area of only 0.22 m2. (b) what is the power of the aircraft's reflection? assume that the beam is reflected uniformly over a hemisphere. back at the radar site, what are (c) the intensity, (d) the maximum value of the electric field vector, and (e) the rms value of the magnetic field of the reflected radar beam?
