Abstract:

The theory developed in this report applies to any type of process or source. It is shown that the coherence properties of electromagnetic waves bear a direct relationship to their information carrying capacity. A number of examples are worked out of the coherence properties of monochromatic and polychromatic waves emitted by either point sources or extended objects. The effect of aperture limitation on the coherence properties of the image of the above sources is also investigated. Part II is concerned with the estimation of the dynamic states of a nonlinear diffential equation which is quasi-linear in the vector function x fx. To demonstrate the nonlinear estimation procedure, an algorithm was programmed for a digital computer which solves the equations for estimation of the dynamic states of an unguided reentry space vehicle.
