Fly Eye radar: detection through high scattered media 

Paper 10188-32

Author(s): Pavlo A. Molchanov, Ashok Gorwara, Planar Monolithic Industries, Inc. (United States) 

Fly Eye radar is multi-beam, monopulse, multi-frequency system. Multiple angularly shifted directional antennas are coupled with wide/multi band receivers and separately connected to processor by digital interface. Application of monopulse method with overlap closely spaced antenna patterns provides high accuracy measurement of amplitude, phase, and direction to signal source. Fly eye non-scanning multi-frequency radar system provides simultaneous continuous observation of multiple targets and wide possibilities for stepped frequency, simultaneous frequency, chaotic frequency sweeping waveform (CFS), polarization modulation for reliable object detection. Proposed c-band fly eye radar demonstrated human detection through 40 cm concrete brick wall with human and wall material spectrum signatures.

Handheld microwave bomb-detecting imaging system 

Paper 10188-37

Author(s): Pavlo A. Molchanov, Ashok Gorwara, Planar Monolithic Industries, Inc. (United States) 

Existing x-ray technology is limited to short range applications only, and expose users to harmful radiation. Proposed system is based on the application of a long wavelength low power monopulse RF/Microwave imaging system with enhanced camouflage and foliage penetration. UWB Software Defined Receiver coupled with the object and reference antennas can record real time digital hologram which consists of amplitude and phase information of the diffracted RF/Microwave signals. Information about shape of object is contained within the electromagnetic phase front and can be restored from recorded digital hologram. Spectrum signature will provide information about material of object.
