Abstract: An airborne system and method for the characterization and measurement of radiating systems or antennas (5), including: an aerial module (1) including a unit for measuring electromagnetic emissions (11), which captures the electromagnetic field (E) radiated by the radiating system or antenna (5), and a positioning and guiding system (13) with an accuracy equal to or less than 3 cm; and a ground station (2) including a unit (23) for processing the electromagnetic emission measurements, which processes the measurements using a set of algorithms for processing electromagnetic emission measurements (25). Also, a method for measuring and characterizing radiating systems or antennas (5). The invention is suitable for use in sectors that require antennas to be characterized and measured, such as, for example, radar and radio navigation facilities, terrestrial- and satellite-based telecommunications systems, or terrestrial broadcasting facilities.

Abstract: In some aspects, the disclosure is directed methods and systems for screening an unconstrained subject. A plurality of transmitters may be spatially distributed on two sides along a path of movement of a subject. Each of the transmitters may transmit, in sequence, radiation to be scattered from the subject. A plurality of sensors may be spatially distributed on the two sides and coherently configured with respect to the plurality of transmitters. The plurality of sensors may collect measurements of scattered radiation corresponding to the radiation transmitted by each of the plurality of transmitters. An imaging module may generate, based on the collected measurements, a two-dimensional or three-dimensional reconstruction estimate of body surface of the subject with one or more attached foreign objects.

Abstract: In some aspects, the disclosure is directed methods and systems for establishing a wideband radar system for imaging. A receiver of a radar imaging system may receive a set of phase measurements for each of a plurality of frequency bands, each of the plurality of frequency bands established by up-converting or down-converting a base frequency band. A phase adjuster of the radar imaging system may identify, from each region of overlap between consecutive frequency bands of the plurality of frequency bands, a phase difference between corresponding sets of the phase measurements. The phase adjuster may adjust one or more sets of the phase measurements based on the identified phase differences to generate an image across the plurality of frequency bands.

Abstract: A system and method for determining a volume of a body, body part, object, or stimulated or emitted field and identifying surface anomalies of the object of interest. A first set of image data is acquired corresponding to the object of interest from an imaging device. Depth data and a second set of image data is acquired from a structured light emitter including at least one sensor. A processor receives the first and second set of image data and based thereon, generates a resultant image including the depth data. A display is configured to display the resultant image to identify surface anomalies. A geometric model is applied to the resultant image to calculate a volume of the object of interest.
