Abstract: A system-of-systems avionics architecture that is compatible with futuristic multi-function multi-platform sensor applications. The method and device of the invention is based on localized “adaptive” waveform and spectrum allocation for ultra-wideband radio frequency and microwave signals. The invention includes a plurality of system platforms with each platform comprising a common radio frequency front end for receiving ultra-wideband signals, a common radio frequency back end for transmitting ultra-wideband signals and a plurality of sensors for exchanging data between platforms.

Abstract: Bistatic/multistatic radar system concept for purposes of interrogating difficult and obscured targets in urban environments via the application of low-altitude “smart” or “robotic-type” unmanned air vehicle platforms. A significant aspect of the invention is the formulation of a unmanned air vehicle system concept that implements self-adaptive positional adjustments based on sensed properties such as phase discontinuities of the propagation channel.

Abstract: Bistatic radar compatible for investigating the employment of a high-altitude UAV working in tandem with a group of low-altitude UAVs. The bistatic radar is divided into a position-adaptive bistatic mode and a close-range monostatic mode. In position-adaptive (robotic) bistatic mode, each low-altitude UAV estimates a new parameter denoted as the differential path length to adaptively implement self-adjustments in position. This approach provides each UAV with the potential for looking down the “throat” of an obscuration channel. In the event that a particular low-altitude UAV detects an obscuration channel, the low-altitude UAV will transfer to a close-range monostatic mode in an effort to interrogate the obscuration channel for targets.
