N2 - Atmospheric turbulence reduces the ability to recognize motion characteristics of intensity profiles and causes a “frequency shift deformation” in time-frequency curves in theory. The scanning imaging technology and the micro-Doppler effect are combined to introduce the concept of micro-Doppler frequency shift imaging, providing a solution for dealing with complex environments such as atmospheric turbulence. We conducted experiments on the micro-Doppler frequency shift of rotating targets scanned by a transceiver co-location system. The imaging algorithm employs Delaunay triangulation, cubic Bézier interpolation, and heatmap visualization. Both simulation and experiment results confirm its capability to analyze target shape and motion characteristics, along with robustness against environmental interference.
