    • A spinning strip aperture imaging radiometer sensor system and data processing methods for detecting moving objects derived from a plurality of image frames acquired by a strip aperture imaging sensor. A moving object in any individual image frame results in a motion smear signature in the total synthesized image. The motion smear signature is processed to detect the moving objects. One embodiment of the system comprises a rotating strip aperture telescope, a two dimensional detector array that detects images in the telescope's focal plane, a rotation compensation device that prevents rotational smear during integration time of detectors of the array, a signal processor that records a plurality of image frames of a scene imaged by the telescope as it rotates around its optical axis, and that implements method(s) for detecting the moving objects present in the recorded images. A hierarchy of moving object detection processors and methods 20 is disclosed that includes spatial, temporal, spatial frequency, and temporal frequency domain detection processors, and is compatible with multi-spectral background rejection techniques. Selection of the appropriate processing procedure and method depends upon the scenario, and the effective signal to noise ratio characteristics of the moving object.

    • A method for transmitting data contained in a document between a scanning device and a plurality of heterogeneous receiver destinations, each respective receiver destination being capable of receiving scanned information in a specific data form, is set forth. In a first step, a plurality of heterogeneous receiver destinations are selected. Next, an acceptable data form for each receiver destination is determined. The document is then scanned once to convert the document into electronic data. The electronic data is then used to create a respective electronic data file for each receiver destination, each file converted to a data form appropriate to its corresponding receiver destination. The electronic data files are then transmitted to their respective receiver destinations. In a system including a scanning device connected to at least one receiver capable of receiving scanned information as electronic files, a scanning device transmission arrangement is also set forth. The arrangement includes a processor for storing, retrieving, and selecting a plurality of heterogeneous receiver destinations. A scanning device is provided for converting the document into electronic data. Also included is a communication device for establishing contact with a selected plurality of heterogeneous receiver destinations and for transmitting data created from a scanned document to the selected plurality of heterogeneous receiver destinations simultaneously.

    • A spinning strip aperture imaging radiometer sensor system and data processing method for synthesizing a super-resolved scene estimate (super-resolved scene) from a plurality of image frames acquired by the strip aperture imaging sensor system. One embodiment of the imaging system comprises a rotating strip aperture wide field of view telescope, a two dimensional detector array for detecting images in the focal plane of the telescope, rotation compensation apparatus for preventing rotational smear during the integration time of the detectors, a signal processor for recording a plurality of image frames of a scene that is imaged by the telescope as it rotates around its optical axis, and an estimation processor employing the present method for synthesizing the super-resolved scene estimate from the recorded images. The super-resolved image synthesis method uses a plurality of rotating strip aperture measurements within the strip aperture passband and within the passband of an equivalent bandlimited synthesized full circular aperture to estimate the spatial frequency information outside the total measurement passband, and/or outside the passband of the equivalent bandlimited synthesized full circular aperture, as well as within the equivalent bandlimited passband. Knowledge of the spatial response function of the strip aperture, the spatial response function of the detector array, noise statistics, and the temporal registrations of each of the recorded strip aperture images permits synthesis of the super-resolved full aperture image by the sensor system and image synthesis method. The super-resolved image synthesis method may be employed in the spatial domain, the spatial frequency domain, or both.
