A computer-implemented method for estimating a parameter of an object, particularly for classifying an object and/or characterizing a surface of an object, within a scene, specifically a volume, the method comprising: receiving, by at least one data processor, data characterizing a measurement for the scene received by a plurality of sensor elements forming a sensor array, wherein the measurements represent radiation transmitted by a radiative imaging system and reflected by the object within the scene; and being characterized by: determining, using the at least one data processor and the received data, intermediate scattering coefficients by applying to the received data a mapping of a plurality of scene sub-domains to the plurality of sensor elements, the intermediate scattering coefficients determined for each of a plurality of measurement sub-domains, each measurement sub-domain comprising a grouping of measurements received by a subset of the plurality of sensor elements forming the sensor array; and estimating, using the at least one data processor and the intermediate scattering coefficients, a parameter of an object within the scene, wherein the intermediate scattering coefficients represent reflective properties of the plurality of scene sub-domains with respect to interrogation by sensor elements corresponding to the measurement sub-domain. receiving, by at least one data processor, data characterizing a measurement for the scene received by a plurality of sensor elements forming a sensor array, wherein the measurements represent radiation transmitted by a radiative imaging system and reflected by the object within the scene; and being characterized by: determining, using the at least one data processor and the received data, intermediate scattering coefficients by applying to the received data a mapping of a plurality of scene sub-domains to the plurality of sensor elements, the intermediate scattering coefficients determined for each of a plurality of measurement sub-domains, each measurement sub-domain comprising a grouping of measurements received by a subset of the plurality of sensor elements forming the sensor array; and estimating, using the at least one data processor and the intermediate scattering coefficients, a parameter of an object within the scene, wherein the intermediate scattering coefficients represent reflective properties of the plurality of scene sub-domains with respect to interrogation by sensor elements corresponding to the measurement sub-domain. determining, using the at least one data processor and the received data, intermediate scattering coefficients by applying to the received data a mapping of a plurality of scene sub-domains to the plurality of sensor elements, the intermediate scattering coefficients determined for each of a plurality of measurement sub-domains, each measurement sub-domain comprising a grouping of measurements received by a subset of the plurality of sensor elements forming the sensor array; and estimating, using the at least one data processor and the intermediate scattering coefficients, a parameter of an object within the scene, wherein the intermediate scattering coefficients represent reflective properties of the plurality of scene sub-domains with respect to interrogation by sensor elements corresponding to the measurement sub-domain.
