Since over half-a-century ago, the initial use of ground radars was primarily long-range strategic aerial surveillance from fixed and elevated sites. As can be expected, the equipment was expensive and large. The progress in RF technology on one hand, and the arising need for detection of combat threats by tactical levels on the other, led to the development over the last three decades of artillery/missiles locating radars (e.g. TPQ-36/37 FIREFINDERs, GIRAFFE) and medium/short-range air defence radars (e.g. MPQ-64 SENTINEL). After cycles of technology injection, upgrades and introduction of modern systems, today's radars can typically perform both air defence and fire detection/location missions (i.e. TPQ-53, TPS-80 G/ATOR, and ELM-2084 MMR).
