A Comparison of Monopulse and Interferometric Systems
Abstract
The angular error performance of monopulse and interferometric systems is derived and used as a basis to compare the characteristics of the two techniques. The angular error performance of the interferometric system is achieved at the expense of ambiguities in its response and the use of monopulse circuitry with the interferometric elements was investigated as a means of resolving the ambiguities, a technique which appears to be previously unexplored. A statistical analysis was developed which expresses the probability of correct ambiguity resolution in terms of the monopulse performance and the relative size between the interferometric antenna and its baseline. The angular coverage and signal sensitivity of the two systems are dictated by their respective antenna characteristics; for the same angular error performance, the interferometric system achieves a larger coverage at the expense of signal sensitivity. The choice of a particular technique for a specified application depends on the interplay of the system requirements and the characteristics of the two techniques. (Author)
