CHAPTER 18 TRACKING RADARDean D. HowardLocus, Inc., a subsidiary of Kaman INTRODUCTIONA typical tracking radar has a pencil beam to receive echoes from a single targetand track the target in angle, range, and/or doppler. Its resolution cell definedby its antenna beamwidth, transmitter pulse length, and/or doppler bandwidth is usually small compared with that of a search radar and is used to exclude un-desired echoes or signals from other targets, clutter, and countermeasures. Elec-tronic beam-scanning phased array tracking radars may track multiple targets bysequentially dwelling upon and measuring each target while excluding other echoor signal of its narrow beamwidth, typically from a fraction of 1 to 1 or 2 , atracking radar usually depends upon information from a search radar or othersource of target location to acquire the target, , to place its beam on or in thevicinity of the target before initiating a track.
