SINGLE CHANNEL MONOPULSE TECHNIQUES
Abstract
This report describes the results of a study and investigation to obtain a technique for processing both the communications and tracking signals in a single receiver in a satellite communications system. Various techniques were studied, with emphasis on Pseudo-Monopulse, Frequency Division Multiplexing, Time Division Multiplexing, and the Automatic Manual Simulator (AMS), a mechanical scanning method. All systems were analyzed to determine basic feasibility. Detailed analyses of the most promising techniques (Pseudo- Monopulse, AMS, FD), were made. Major factors considered were: performance in the presence of thermal noise, errors due to phase and amplitude unbalance, normalization (dependence of pointing error on received signal strength), acquisition problems, and equipment complexity. A relative evaluation of all Single Channel Monopulse Tracking Receiver (SCMTR) techniques, including three channel monopulse for comparison, was made, and Pseudo-Monopulse was shown to offer the most advantages for the stipulated conditions. A complete Pseudo- Monopulse receiver design was accomplished and is included in this report. The AMS technique was shown to be useful when equipment simplicity is the prime goal.
