Radar MASINT — is one of the subdisciplines of Measurement and Signature Intelligence (MASINT) and refers to intelligence gathering activities that bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT),… … Wikipedia
Radar cross section — (RCS) is a measure of how detectable an object is with a radar. For example a stealth aircraft (which is designed to be undetectable) will have design features that give it a low RCS, as opposed to a passenger airliner that will have a high… … Wikipedia
radar — /ray dahr/, n. 1. Electronics. a device for determining the presence and location of an object by measuring the time for the echo of a radio wave to return from it and the direction from which it returns. 2. a means or sense of awareness or… … Universalium

blind ranges — Ranges in pulse Doppler radars for which the pulse transit time is such that echoes are received during the time the receiver is blanked off for transmitting a pulse. Aircraft, as a tactical measure, try to intrude at this speed to avoid… … Aviation dictionary
History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… … Wikipedia
Over-the-horizon radar — US Navy Relocatable Over the Horizon Radar station Over the horizon radar, or OTH (sometimes also beyond the horizon, or BTH), is a design concept for radar systems to allow them to detect targets at very long ranges, typically up to thousands of … Wikipedia
Passive radar — systems (also referred to as passive coherent location and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non cooperative sources of illumination in the environment, such as… … Wikipedia
