TCT Algorithm for Broadband DOA Estimation with Code Implementation

The TCT algorithm for broadband Direction of Arrival (DOA) estimation is a sophisticated method for measuring signal arrival angles. When initially downloaded from this website, the program encountered runtime errors due to implementation issues in the signal generation component. Through code analysis, I identified that the linear frequency modulation (LFM) signal generation module required optimization to properly handle waveform parameters and timing sequences. The modifications involved adjusting the chirp signal's instantaneous frequency calculation and ensuring proper sampling rate synchronization with the processing algorithm. After refining the LFM generation function to maintain phase continuity and amplitude consistency, the program now executes successfully, demonstrating accurate DOA estimation capabilities for broadband signals across multiple frequency bins. The enhanced implementation maintains the core TCT algorithm structure while improving numerical stability through better signal preprocessing.
