Abstract: A method and system is provided for obtaining data indicative of at least one characteristic of a continuous medium or at least one localized target located within a predetermined volume of space. The system includes a sensor configuration and a processing circuit. The sensor configuration includes a plurality of sensors for acquiring a plurality of signals from the continuous medium or the target(s). The plurality of sensors have centers spatially separated from each other in at least one spatial dimension. The processing circuit is configured for obtaining data indicative of the characteristic or characteristics of the medium or the target by calculating a plurality of powered weighted increments using the plurality of signals acquired by the sensor configuration and by using a plurality of models for relating the plurality of powered weighted increments to the characteristic or characteristics of the medium or the target.

Abstract: A method and system is provided for obtaining data indicative of at least one characteristic of a continuous medium or at least one localized target located within a predetermined volume of space. The system includes a sensor configuration with at least one sensor for acquiring a plurality of signals from the continuous medium or the target. Each one of the plurality of signals is centered at a respective distinguishable frequency. The system also includes a processing circuit for obtaining the data indicative of the characteristic of the continuous medium or the target by calculating a plurality of powered weighted increments using the plurality of signals acquired by the sensor configuration and by relating the plurality of powered weighted increments to the characteristic of the continuous medium or the target using a plurality of models.
