Ultrawideband radar motion sensors strategically placed in an area of interest communicate with a wireless ad hoc network to provide remote area surveillance. Swept-range impulse radar and a heart and respiration monitor combined with a motion sensor further improves discrimination.
Spatially Adaptive Migration Tomography for Multistatic GPR Imaging

U.S. Patent 8,508,403 B2
August 13, 2013
This imaging and detection system is used to detect the presence of subsurface objects within a medium. In some embodiments, the imaging and detection system operates in a multistatic mode to collect radar return signals. An array of transceiver antenna pairs generates these signals. The array is positioned across the surface and travels down the surface. The imaging and detection system preprocesses the return signal to suppress certain undesirable effects. The system then generates synthetic aperture radar images from real aperture radar images generated from the preprocessed return signal. The system postprocesses the synthetic aperture radar images to improve the detection of subsurface objects. It also identifies peaks in the energy levels of the postprocessed image frame, which indicate the presence of a subsurface object.

U.S. Patent 8,514,475 B2
August 20, 2013
This electro-optic device has an electro-optic crystal with a predetermined thickness and first and second faces. A first electrode substrate is positioned opposite the first face. This first electrode substrate includes a first substrate material with a first thickness and a first electrode coating coupled to the first substrate material. A second electrode substrate is positioned opposite the second face. This second electrode substrate includes a second substrate material with a second thickness and a second electrode coating coupled to the second substrate material. A voltage source is electrically coupled to the first and second electrode coatings.
