Paper Abstract

Blackbody radiation laws for photons and the simple power transfer equation are used to calculate the number of photons originating at a representative nearby solar system and incident on a unit area collecting aperture near Earth. The signal due to the planet is prohibitively small in comparison with that due to a star. The radiometric signal- to-noise ratio of 10-5 necessitates an indirect, non-imaging detection scheme, such as interferometry, that searches for a single spatial frequency corresponding to the star-planet vector distance.
