Circle Diagram Applied to Monopulse

Quite a lot of reports on monopulse systems have been published in recent days. The analysis has mostly been confirmed to pure amplitude sensing or pure phase sensing. If amplitude and phase are allowed to vary simultaneously the general formulas will be rather lengthy. The situation is suggestive of transmission line calculus where the usefulness of the Smith chart is well known. In a slightly modified form this chart is a convenient aid in analyzing the influence of various parameters in the most common monopulse systems.
