In response to the characteristics of high mobility of combat platforms, mechanical motion, complex terrain, and dynamic external environments, achieving high-precision antenna pointing is crucial for vehicle-mounted phased array radars to ensure accurate target positioning. Focusing on the antenna of vehicle-mounted phased array radars, this study investigates the sources of mechanical pointing errors and establishes error models for evaluation and sensitivity analysis. Combined with the engineering feasibility, the precision decomposition of each device is carried out, sensors are deployed to monitor deviations, while design-based precision compensation and safeguards are implemented from the design point of view. Precision testing is conducted for individual components and the integrated system under segmented conditions. Combined with the instrument accuracy and test data, antenna mechanical pointing errors are compensated. Validation is performed through two types of far-field experiments. Data comparison demonstrates that the proposed analysis and testing methodology enhances the accuracy and reliability of antenna mechanical pointing in vehicle-mounted phased array radars, offering valuable insights for engineering applications.
