In order to improve the measurement accuracy of wide-beam phase detection technology, this paper proposes anew sub-aperture stitching algorithm. The algorithm stitches the phase information of multiple small apertures together to form alarger field of view phase image, thereby improving the spatial resolution and measurement accuracy of phase detection. Through theoretical analysis and experimental verification, this paper proves the effectiveness and practicality of the algorithm, and provides anew idea and direction for the application of wide-beam phase detection technology.
