Title:
レーダ撮像システム、及び、シーンのレーダ反射率画像を再構成する方法
Document Type and Number:
Japanese Patent JP6877647
Kind Code:
B2
Abstract:
A radar imaging system to reconstruct a radar reflectivity image of a scene including an object moving with the scene, includes an optical sensor to track the object over a period of time including multiple time steps to produce, for each of the multiple time steps, a deformation of a nominal shape of the object, and an electromagnetic sensor to acquire snapshots of the scene over the multiple time steps to produce a set of radar reflectivity image of the object with deformed shapes defined by the corresponding deformations of the nominal shape of the object. The system also includes a processor configured to determine, for each of the multiple time steps using the deformation determined for the corresponding time step, a transformation between the radar reflectivity image of the object acquired by the electromagnetic sensor at the corresponding time step and a radar reflectivity image of the object in the prototypical pose, and to combine the radar reflectivity images of the object with deformed shapes transformed with the corresponding transformations to produce the radar reflectivity image of the object in the prototypical pose.
