    摘要: Methods and systems are disclosed for scalable antenna arrays that may be built up using pluggable tiles that have low distortion, flat band high gain, and structured to channelize the signals into narrow bands that may be 40 MHz or even smaller bandwidth apart. Antenna array tiles may employ traveling wave tube (TWT) components and wafer scale arrays. H-topology, equal length, feed networks connect the signals to antenna elements. The fractal-like, recursively repeating at different size scales, structure for the H-tree feed networks, implemented using pluggable tiles, facilitates the scalability of the high gain waveguide antenna array. System integration across the 75-115 GHz spectral band implements scalable aperture architecture with emphasis on addressing considerations of the TX power requirement, feed network, channelizing signals at different frequency bands using specially designed diplexers and combiners, cooling, component placement, and isolation.

    摘要: Systems and methods for screening, where a subject walks through or in front of a passive detector (or scanning unit) to be screened for possession of unauthorized electronics devices, provide for detecting and monitoring electronics systems not authorized to be used in secure areas. By focusing a very narrow beam width antenna array, individuals can be screened who may have concealed electronics devices that can pose danger to the surroundings. There is no need for removing clothing or accessories such as a jacket or backpack, for example. The detection system may include a frequency scanned passive receiver that captures a signal from a detected electronics device, measures its strength, and identifies the device or classifies it according to a pre-determined set of categories (e.g., cellular phone, camera, or global positioning system (GPS)).

Trajectory modeling enables fusing the radar sensor data with optical or thermal imaging data and the trajectory information to display a probable source location of the detected ballistic projectile.
