However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image. Through-the-wall radars can be made with Ultra Wideband impulse radar, micro-Doppler radar, and synthetic aperture radar (SAR). [5] Imaging radar; 3D radar
Radar jamming and deception is a form of electronic countermeasures (ECMs) that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while ...

Employing over 600 employees, it is Australia's largest majority owned defence company. CEA specialises in the design, development and manufacture of radar and communications systems for civil and military applications.
Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see the Melbourne cricket ground and landscapes from various angles.
The Direct Client-to-Client Protocol (DCC) has been the primary method of establishing connections directly between IRC clients for a long time now. Once established, DCC connections bypass the IRC network and servers, allowing for all sorts of data to be transferred between clients including files and direct chat sessions. Client.
AI.24 Foxhunter radar. Much of the radar system and related operational software was developed at the Radar Research Laboratory of GEC-Marconi Elliott Avionic Systems Ltd., initially at the Elliott Automation plant in Borehamwood, Hertfordshire, United Kingdom, and latterly (from 1981 to 2004) as Marconi Avionics at the (formerly the Xerox site of a matrix of interconnected grey portacabins ...
The AN/TPY-2 is a digital antenna array radar, which operates in the 8.55–10 GHz X band. Raytheon builds it as part of an X-band family, along with the National Missile Defense (NMD) X-Band Radar (XBR) and AN/FPS-129 HAVE STARE. [ 5] The use of X band provides better target resolution than lower frequency bands, for example the L band ...
