Battlefield radars perform four core functions: They can detect people or vehicles, aircraft; Rocket Artillery and Mortar (RAM) fire and even equip vehicles to detect incoming ordnance. Armies must often deploy several types of radar to support the manoeuvre force. This could include Ground Surveillance Radars (GSRs) to detect people, vehicles and some low-flying aircraft such as Uninhabited Aerial Vehicles (UAVs). These maybe reinforced with ground-based air surveillance radars to detect hostile fixed- and rotary-wing aircraft, and UAVs at range, together with Weapons Locating Radars (WLRs) to detect incoming RAM fire. Finally, armoured vehicles may use radars to detect incoming munitions to alert their Active Vehicle Self Protection Systems (AVSPSs). Why have radar engineers not developed a standard, deployable radar that could perform most, if not all, these missions? Would this not save on the cost and logistics having to deploy multiple radars for this array of targets?
