Question

Problem 26.47 Two satellites at an altitude of 1000km are separated by 31km Part A If they broadcast 4.0cm microwaves, what minimum receiving dish diameter is needed to resolve (by Rayleigh's criterion) the two transmissions? Express your answer using two significant figures.

Explanation / Answer

Apply s/r = (1.22)(wavelength)/D

31/1000 = (1.22)(.04)/D

D = 1.57 m
