Dual-Baseline Radar Monopulse Angle Measurement with Ambiguity Resolution for Enhanced Accuracy

Recent research demonstrates that employing dual-baseline radar monopulse angle measurement combined with ambiguity resolution techniques can substantially enhance angle measurement accuracy. This approach utilizes the phase difference between two baselines to eliminate angular ambiguities while reducing measurement errors during signal processing. The implementation typically involves cross-correlation algorithms between baseline channels and phase unwrapping techniques to resolve integer ambiguities. Through systematic optimization of radar system parameters and signal processing chain improvements, more accurate and reliable angle measurement results can be achieved. Key functions include baseline calibration, interferometric phase extraction, and ambiguity resolution algorithms using Chinese Remainder Theorem or maximum likelihood estimation. This technology holds broad application potential in aviation, aerospace, and communication systems, providing higher precision data support for various applications requiring precise angular information.
