Abstract: A method and apparatuses may be provided for detection, tracking, and classification of one or more land, maritime, or airborne objects using a real-aperture radar mounted on a parasail airborne platform. Both wide-area and localized radar surveillance can be provided, and the radar can be either a non-coherent radar or coherent radar. A method and apparatus may use a low-cost, rotating, single-beam, non-coherent, X-band radar that is mounted on an unmanned powered parasail and operated remotely like an Unattended Airborne System (UAS). The parasail, which may be expendable or recoverable, manned or unmanned, powered or unpowered, may have a low operational cost, can carry a heavy payload, stay on station for a long time, circle or move to a specified location for surveillance, operate at an optimal altitude and look-angle, and automatically cue or manually steer an EO/IR camera to a target of interest for classification and identification.

Abstract: Methods and apparatuses for providing wide-area surveillance with a radar and/or other sensors from a stratospheric balloon launched from a land or ship platform for detection, tracking, and classification of maritime, land, and air objects such as ships, people/vehicles, or aircraft are described generally herein. In one or more embodiments, an apparatus is battery operated and includes a stratospheric balloon filled that is filled with helium when it is launched and a gondola with a radar system and communication equipment suspended therefrom. When launched, the apparatus can travel with the wind until it reaches an altitude of approximately 68,500 ft., then it can move substantially horizontally with the stratospheric winds until it returns to earth via a parachute. Multiple apparatus launches at periodic intervals can help provide continuous coverage of the surveillance area. The apparatus can be recovered and re-used or can be considered expendable.

Abstract: A land-based Smart-Sensor System and several system architectures for detection, tracking, and classification of people and vehicles automatically and in real time for border, property, and facility security surveillance is described. The preferred embodiment of the proposed Smart-Sensor System is comprised of (1) a low-cost, non-coherent radar, whose function is to detect and track people, singly or in groups, and various means of transportation, which may include vehicles, animals, or aircraft, singly or in groups, and cue (2) an optical sensor such as a long-wave infrared (LWIR) sensor, whose function is to classify the identified targets and produce movie clips for operator validation and use, and (3) an IBM CELL supercomputer to process the collected data in real-time. The Smart Sensor System can be implemented in a tower-based or a mobile-based or combination system architecture. The radar can also be operated as a stand-alone system.

Abstract: A method and an apparatus for detection and tracking of one or more objects in land clutter, including strong clutter and low observable (LO) objects such as a humans, animals, vehicles, and small, low-flying aircraft using a non-coherent radar or the amplitude output of a coherent radar. The preferred embodiment of the method and apparatus uses an X-band, maritime, non-coherent radar and the Doppler spectra computed from the high-frequency amplitude modulations produced by the object interacting with the land-based clutter to determine the presence, velocity, and track of the object.

Abstract: A security device (2) including a substantially transparent material (6) having a first side and a second side. An array of lenses (4) is arranged on the first side of the material (6) and an ablative layer (8), which is reflective or at least partially opaque, is arranged on the second side of the material. The ablative layer has one or more patterns (12, 16) formed by removal of the ablative layer, for example by laser radiation (10, 14). The or each pattern (12, 16) is viewable at a particular viewing angle (?, ?) or range of angles through the array of lenses. Also disclosed is a method of manufacturing a security device.
