Radar Systems

radio detection and ranging

electromagnetic waves as a primary signal

reflections on objects as a secondary signal

large coverage area

detection and tracking of flying objects over long distances

due to the long range, the tracking is rather inaccurate compared to a fire control radar

by the increasing use of Phased-Array-antennae this application is dwindling

US-Group Raytheon

457 km range

antenna measurements 7,3m x 4,3m

on most ships of the U.S. Navy

ever evolving since 1965

range ca. 400km

simultaneous tracking of: > 1000 air targets, 100 surface targets plus 32 jamming channels

generally: guidance of missiles and guns

very high pulse repetition frequency, narrow main beam and short transmission pulses

targeting by search radar, then continuous tracking

nowadays more and more replaced by multi-function radars

phased-controlled array with strong directivity

by bundling the emission energy of single transmitters

control of elements allows combination of search radar and tracking / fire control radar

technology of the future

have several options of detection and tracking of targets / objects as well as active fire control for weapons

active phased array antennas enable modern weapon systems to respond to massive air strikes involving projectiles or missiles with very small effective reflecting cross sections in an environment with heavy jamming
