Overview

Novel methods improve calibration quality in radar systems, suggesting increased usability in various applications.

Key Points

  • This research aims to develop effective calibration methods for multichannel radar systems to improve image quality and operational integrity.
  • Introduced novel calibration methods for antenna array using linear relationships between channel imbalances and image artifacts.
  • Developed an online monitoring procedure for continuous quality assessment during radar operation.
  • Validated methods through simulations and measurements on a multichannel radar system.
  • New calibration approach achieved high accuracy with minimal measurement effort and computational cost.
  • Online monitoring reliably detected minor calibration degradations under outdoor conditions.
  • Eliminated the need for complex setups like anechoic chambers, thereby broadening accessibility to radar calibration.
