Antenna Control Revolution:Pioneering Design for DWR Systems

This research focuses on enhancing the Antenna Control System for a Doppler Weather Radar (DWR). The current system employs servo motors to manage the antenna's azimuth and elevation angles, utilizing absolute angular shaft encoders to calculate position errors. It offers two operational modes: Local and Remote. In Local mode, operators can manually control antenna velocity in both axes for diagnostic purposes, while Remote mode involves the Servo Control Electronics unit overseeing velocity based on input from the Radar Controller.The proposed work aims to create a microcontroller-based Servo Controller with an integrated graphical user interface (GUI). This controller will enable configuration of the servo subsystem, execution of operations, and control of features such as the scan generator, position loop, and command reception. It will acquire encoder data, calculate position loop errors, and employ trapezoidal velocity control. The undertaking scope encompasses testing, troubleshooting, and maintaining the antenna servo control system using the proposed controller with GUI, ultimately enhancing the overall functionality and efficiency of the DWR system.
