研究目的
Investigating the behavior of an angle tracker in a multi-target environment when angle separation is not the limiting factor in signal strength, focusing on the impact of angle error signal normalization by an Automatic Gain Control (AGC) on track loop dynamics.
研究成果
The study successfully demonstrated how angle error signal normalization by an AGC impacts track loop dynamics in a dual target scenario, showing that the behavior depends on the Doppler frequency separation of the targets relative to the AGC bandwidth. The theoretical and simulation results agreed well, with modifications to the theoretical model improving the match with simulation data.
研究不足
The study is limited to a theoretical and simulation-based analysis, without physical experimentation. The impact of angle track dynamics on the interaction between the angle tracker and AGC was not fully explored.
