Average Monopulse Angle Tracking Response to Two Unresolved Sources

Theoretical equations for the average monopulse ratio response of a monopulse seeker, when tracking in angle two unresolved sources, have been applied to the case where the two sources may be either both passive, both active, or one passive and the other active. The theoretical results for four particular cases of two-source targets are derived to illustrate the effect on the average angular response of the shape of the sum pattern and of the statistical properties and magnitude and separation of the two sources. The theoretical results are verified with the results of digital computer simulation.
