Phase Unwrapping Techniques

Phase unwrapping is a process used in signal analysis to reconstruct the original phase information from measurements that are limited to a certain range (often -π to π). When signals are captured, their phase can appear "wrapped" because values exceeding this range are folded back into it, creating discontinuities. Unwrapping techniques aim to remove these jumps and recover the true phase by analyzing patterns and using mathematical algorithms. This process is essential in applications like imaging, radar, and interferometry, enabling accurate interpretation of signals for precise measurements and imaging.
