Two satellites at an altitude of 1200km are separated by 25km . A).If they broadcast 3.4cm microwaves, what minimum receiving dish diameter is needed to resolve (by Rayleigh's criterion) the two transmissions?
The telescopes on some commercial surveillance satellites can resolve objects on the ground as small as 91 cm across (see Google Earth), and the telescopes on military surveillance satellites reportedly can resolve objects as small as 14 cm across. Assume first that object resolution is determined entirely by Rayleigh's criterion and is not degraded by turbulence in the atmosphere. Also assume that the satellites are at a typical altitude of 403 km and that the wavelength of visible light is...
