Ultra-wideband pulse radar is a promising technology for the imaging sensors of rescue robots operating
in disaster scenarios, where optical sensors are not applicable because of dark smog or high-density gas. For the above application, while one promising ultra-wideband pulse radar imaging method for a target with arbitrary motion has already been proposed with a compact observation model, it is based on an ellipsoidal approximation of the target boundary, and is thus hardly applicable to complex target shapes, particularly when targets have specular surfaces or surface edges. As a substantial solution to this difficulty, we have already proposed a non-parametric and robust imaging method for a target with arbitrary motion including rotation and translation using multi-static radar, which is based on the matching of target boundary points obtained by range points migration method extended to this model. In the case of multiple moving targets, its estimation accuracy is however degraded due to an interference effect from each target. To tackle the above problem, this paper introduces the interference suppression and Envelope image interpolation as pre-processing of the motion estimation. Results from numerical simulations show that the proposed method accurately estimates the motions and shapes of the multiple moving targets |
