A POLARIZATION-DIVERSITY SIMULTANEOUS-LOBING ANGLE-TRACKING RECEIVER
Abstract
A simultaneous-lobing angle-tracking receiver is described, operating in the 225-260 mc telemetry band and employing polarization diversity. Its operation is considered primarily in the context of the Mercury range and tracking of the Mercury capsule. Several methods of providing diversity are briefly considered, and ways of implementing the phase shifts required at one polarization for coherent signal addition are discussed. A prototype receiver is briefly described although circuity which may be somewhat novel is covered in greater detail. No attempt was made to include all of the sophistication one might expect in such a receiver; circuits were simplified in some areas where, for example, a manual control can replace an automatic function and reduce complexity. Some conclusions are drawn as to how this receiver might perform in the Mercury environment. (Author)
