Resolution in the case of aperture synthesis in diversity systems
Abstract
The ambiguity-function approach is used to determine the resolving power that can be achieved by means of inverse aperture synthesis in active and passive diversity systems. Directions of the moving target for which the best resolution is obtained are determined, and expressions are obtained for the corresponding resolving powers. It is shown that the ambiguity functions obtained for aperture synthesis in passive and active systems have practically the same form. The only difference is that the respective formulas for phase difference depend in different ways on the distance to the target.
