Abstract
This paper describes a technique to detect and characterize Near Earth Asteroids (NEAs), by using a formation of telescope-carrying cube-sats that observe the intensity patterns of stellar occultations. Advanced optical processing of the recorded intensity data is employed to deduce the size, shape, and albedo of detected NEAs. The te clinique would greatly extend conventional occultation technology to produce sharp silhouettes of NEAs even when their shadows in starlight are heavily diffracted. The work concentrates on asteroids that are small enough that only a small fraction have been detected, yet are large enough to cause significant destruction in the event of an Earth impact.
