Abstract
Data is received characterizing a plurality of measurements for a scene received by a plurality of sensor elements forming a sensor array. A plurality of scene sub-domains is mapped to the plurality of sensor elements. A plurality of voxels associated with one of the plurality of scene sub-domains is mapped to a plurality of measurement sub-domains. One or more scattering coefficients of the scene is determined by applying the mapping to the received data. Related apparatus, systems, techniques, and articles are also described.
Claims31
A method for implementation by at least one data processor forming part of at least one computing system, the method comprising:
- receiving, by the at least one data processor, data characterizing a plurality of measurements for a scene received by a plurality of sensor elements forming a sensor array;
- mapping, using the at least one data processor, a plurality of scene sub-domains to the plurality of sensor elements, a scene sub-domain of the plurality of scene sub-domains including a plurality of associated voxels that are a subset of voxels in the scene;
- mapping a plurality of voxels associated with one of the plurality of scene sub-domains to a plurality of measurement sub-domains, a measurement sub-domain of the plurality of measurement sub-domains including measurements of a plurality of associated sensor element that are a subset of sensor elements in the sensor array;
- and
- determining, using the at least one data processor, one or more scattering coefficients of the scene by at least applying the mapping to the received data.
A non-transitory computer readable storage medium comprising executable instructions which when executed by at least one data processor forming part of at least one computing system, result in operations comprising:
- receiving, by the at least one data processor, data characterizing a plurality of measurements for a scene received by a plurality of sensor elements forming a sensor array;
- mapping, using the at least one data processor, a plurality of scene sub-domains to the plurality of sensor elements, a scene sub-domain of the plurality of scene sub-domains including a plurality of associated voxels that are a subset of voxels in the scene;
- mapping a plurality of voxels associated with one of the plurality of scene sub-domains to a plurality of measurement sub-domains, a measurement sub-domain of the plurality of measurement sub-domains including measurements of a plurality of associated sensor element that are a subset of sensor elements in the sensor array;
- and
- determining, using the at least one data processor, one or more scattering coefficients of the scene by at least applying the mapping to the received data.
A system comprising:
- a plurality of panels having one or more sensor elements;
- memory and at least one data processor forming part of at least one computing system which implements operations comprising:
- receiving, by the at least one data processor, data characterizing a plurality of measurements for a scene received by a plurality of sensor elements forming a sensor array;
- mapping, using the at least one data processor, a plurality of scene sub-domains to the plurality of sensor elements, a scene sub-domain of the plurality of scene sub-domains including a plurality of associated voxels that are a subset of voxels in the scene;
- mapping a plurality of voxels associated with one of the plurality of scene sub-domains to a plurality of measurement sub-domains, a measurement sub-domain of the plurality of measurement sub-domains including measurements of a plurality of associated sensor element that are a subset of sensor elements in the sensor array;
- and
- determining, using the at least one data processor, one or more scattering coefficients of the scene by applying the mapping to the received data.
