A Novel Mutual Positioning Method for Multi-view Through-the-Wall Imaging Radar
摘要
This paper deals with the problem of spatial registration for multi-view through-the-wall imaging radar (TWIR) and proposes a novel mutual positioning method under multi-view observation conditions. Specifically, first, the extra distance induced by the walls is calculated and compensated by the wall parameter estimation method based on the reflected echoes from the different surfaces. Then, the coordinates of the different TWIRs are calculated by the transmission signals. In this way, the relative coordinates and rotation angles can be aligned into an absolute coordinate system, so that radar localization is complete. Finally, the effectiveness of the method is verified by the electromagnetic simulation data.
