Abstract: An electronic circuit combines two or more individual wideband RF receivers or transceiver band circuits to produce a usable instantaneous bandwidth that is wider than the bandwidth of the individual band circuits. The electronic circuit overcomes the difficulties of combining bands to provide low signal distortion across the band edges and throughout the combined instantaneous bandwidth of the two or more individual band circuits. This electronic circuit utilizes an amplitude, time delay, and phase adjustment procedure that uses associated adjustable circuitry to eliminate misalignments between the two or more individual band circuits.

Abstract: A system for detecting explosive materials. The system includes radiated high power electromagnetic radiation at one or more frequencies in the millimeter wave spectrum or above to interact with a sample and be reflected therefrom. The system also includes at least one electromagnetic sensor to measure emissions at harmonic frequencies and characteristics unique to one or more explosive materials. The system also includes a processor to collate and maintain a lookup table to identify specific explosive material types.
