Abstract: An apparatus for and method of employing synthetic aperture radar (SAR) images to automatically classify a target comprising emitting and collecting SAR signals at a plurality of squint angles, forming a plurality of SAR images of the target from the collected signals, the plurality of SAR images substantially having tilt angle diversity, automatically classifying the target from each of the plurality of SAR images, and generating a most probable target classification from the classifications of the plurality of SAR images.

Abstract: A navigation system includes a navigation device that communicates with a data processing system. The navigation device includes one or more movement detectors that are configured to generate data that are indicative of movement of the navigation device, and a transmitter that is communicatively coupled to the one or more movement detectors. The transmitter is configured to transmit a signal that contains the movement data using a wireless communication protocol. The data processing system includes a receiver that is responsive to the signal from the navigation device and a processor that is communicatively coupled to the receiver. The processor is programmed to process the data to compute a location, position, and/or orientation of the navigation device.

Abstract: A power controller for a mobile terminal variable gain amplifier (VGA). A controller consistent with the invention controls VGA output using a feedback error signal established based on the difference between a signal representative of the VGA output and a signal representative of a target output. The error signal causes convergence of the VGA output to the target output based on a magnitude of the difference. A method of controlling the output of a variable gain amplifier in a mobile terminal is also provided.
