41pencil beam — a cone shaped radar beam. [1945 50] * * * …
42main-beam killing — An ECCM (electronic counter countermeasure) technique in which the main radar beam is switched off but detection is continued by using side lobes …
432D-Radar — Radargeräte werden häufig anhand der Anzahl der zu messenden Koordinaten in zwei Kategorien unterteilt. Radargeräte, die nur Entfernung und Seitenwinkel messen, werden als zweidimensionale oder 2D Radargeräte bezeichnet. Radargeräte, die neben… …
44bent beam, bent course — Radar or radio beams significantly diverted from a straight line resulting from topography, hostile ECM (electronic countermeasures), or any other action …
45Secondary surveillance radar — SSR antenna of Deutsche Flugsicherung at Neubrandenburg, in Mecklenburg/Western Pomerania Secondary surveillance radar (SSR)[1] is a radar system used in air traffic control (ATC), that not only detects an …
46Monopulse radar — is an adaptation of conical scanning radar which sends additional information in the radar signal in order to avoid problems caused by rapid changes in signal strength. The system also makes jamming more difficult. Most radars designed since the… …
47History 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.… …
48Clutter (radar) — Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious… …
49Semi-active radar homing — Semi active radar homing, or SARH, is a common type of missile guidance system, perhaps the most common type for longer range air to air and surface to air missile systems. The name refers to the fact that the missile itself is only a passive… …
503D radar — provides for radar coverage on three dimensions unlike the more common 2D radar. While the normal 2D radar provides range and azimuth, the 3D radar provides elevation information with range and azimuth. Applications include weather forecasting,… …
