Enhanced Core Technology | More Accurate Perception! Calterah’s Single Snapshot DoA Estimation Method Based on Deep Learning Enhanced Core Technology | More Accurate Perception! Calterah’s Single Snapshot DoA Estimation Method Based on Deep Learning Original Calterah Microelectronics Technology Calterah Microelectronics Technology Calterah Microelectronics Technology January 15, 2026 11:32, Shanghai Immersive Reading in Novel Reader Array defects, complex covariance matrix inversion, inadequacy of real-world data adaptability… these challenges have consistently limited the performance ceiling of Direction of Arrival (DoA) estimation. So, how can Frequency Modulated Continuous Wave (FMCW) radar, with a limited number of antennas, achieve accurate DoA estimation to enhance radar sensing capabilities? In this technical article, we will deeply analyze the “creative core thinking” proposed by Calterah: A DoA estimation method based on deep learning, which cleverly reconstructs the inverse
