Abstract
A new predetection combiner has been devised which has superior performance to predetection and baseband combining systems previously used in troposcatter systems. In-phase addition at intermediate frequency is accomplished using a heterodyne phase stripping technique. A two-channel receiver using this principle has been tested, and performance is in reasonable agreement with theory. Performance was, in general, superior to a dual channel baseband combiner.
