This thesis mathematically describes the overall behavior of a monopulse angle tracker as it relates to transitioning to an interfering target signal. The engineering community is confident in its assessment on how an angle tracker will perform in a multi-target environment as the target-to-tracker range decreases, causing targets to leave the tracker antenna beam. When one target signal dominates due to the angular separation of the targets, the tracker will center on the dominating signal. It is not well understood how the tracker will behave when angle separation is not the limiting factor in signal strength. Analytical studies presented in this thesis will evaluate how the open-loop error signal normalization impacts the track loop dynamics. Specifically, if the error signal is normalized by an Automatic Gain Control (AGC), the behavior will depend upon the target Doppler frequency separation of the two targets relative to the AGC bandwidth. Along with verification of the theoretical derivations, simulation efforts will consider multiple target signals within the main beam of the antenna, allowing for a more thorough investigation of closed-loop tracker performance.
