ABSTRACT:
a ratating sensor responsive to infrared or electro-optic radiation has a nearly hemispherical field of view. The sensor comprises a rotating platform (3) supporting a planar multidetector focal plane array (1). The array (1) has three or four sides. Two of the sides are straight lines. One or two sides are portions of conic sections. Individual detectors (2) within the array (1) can be continuous or discrete, and are organized into rows generally following the shape of the conic section(s). In either embodiment, time delay integration is performed row by row within the array (1) so as to equalize the sensitivity and resolution for each portion of the viewed scene. Several arrays (1) can be mounted within the carrier vehicle (8), mounted at different field angles. In this embodiment, the shape of the arrays (1) vary from a sector of a circle to rectangular.
