    Abstract: An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.

    Abstract: Radiation is directed at an object, and radiation scattered by the object is sensed. An angular distribution of scatter in the sensed scattered radiation relative to a path of the radiation directed at the object is determined, and the angular distribution is evaluated. One or more atomic numbers, or effective atomic numbers, of materials composing the object is determined based on evaluating the angular distribution.

    Abstract: A volumetric image of a space is acquired from an imaging system. The space includes an object of interest and another object, and the volumetric image includes data representing the object of interest and the other object. A two-dimensional radiograph of the space is acquired from the imaging system. The two-dimensional radiograph of the space includes data representing the object of interest and the other object. The two-dimensional radiograph and the volumetric image are compared at the imaging system. A two-dimensional image is generated based on the comparison. The generated two-dimensional image includes the object of interest and excludes the other object.

    Abstract: Methods, systems, and apparatus for transmitting a first set of stepped-frequency CW signals having first signal parameters, where the first signal parameters includes a first bandwidth and a first step size between signal frequencies. Detecting reflections of the first set of transmitted CW signals. Identifying an indication of a potential target in a frequency range of the reflections of the first set of transmitted CW signals from the detected reflections of the first set of transmitted CW signals. Determining second signal parameters for a second set of stepped-frequency CW signals in response to identifying the indication of the potential target. The second signal parameters include a second bandwidth and a second step size between signal frequencies, and where the second signal parameters focus on the frequency range in which the indication of the potential target is identified. Transmitting the second set of CW signals.
