Fire-control radar

A fire control radar (FLR, also called " tracking radar ", " tracking radar " or " tracking radar " ) is used for steering of radar guided missiles and anti-aircraft guns. Usually movable - - target with a radar system tracks with the purpose to pass on the determined position of a weapon system manually or automatically: It is a.

Technology

Fire control radars differ in structure and function substantially from search radars. So they can not independently explain objectives usually because their special construction is unsuitable with very high pulse repetition rate, narrow main lobe and short transmission pulses for large-scale target search. Therefore, in addition also has a search radar may be present, which determines the exact position of the target for the fire control radar. Only then will the fire control radar allows to align with the objective to capture it and to pursue continuous ( engl. Tracking). Now, the fire control radar, due to its specific design features (see above), provide continuous target data with very high precision, which are necessary for the control of semi - active, beam -riding or command -guided missiles and can not be supplied by a search radar. Also, anti-aircraft guns and naval guns benefit from the high precision of the target data, as these do now accurate alignment of the pipes possible.

Development

Early systems are mostly CW and FMCW radars. Later pulse radars have been used with special antennas which applied the method of Minimumpeilung. Today, systems are used on the basis of the Doppler pulse or the monopulse method primarily. Furthermore, there is a trend towards multi-function radars, which can combine the functions of search and Feuerleitradaren, about APAR.

In fighter aircraft this merge has already taken place early, as we usually did not have space for two separate radars in the narrow fuselage. However, this leads to a significant reduction in efficiency in the use of some missiles (eg AIM -7 Sparrow ), since the system must constantly switch between fire control and search mode. New multi-function radars as AN/APG-63 ( V) 2 provide a solution to this problem dar.

In more recent times come in Feuerleitradaren increasingly phased array antennas used, whose electronic beam scanning and bundling allows a faster and more accurate target tracking.
