The probability of detecting a given target at a given range any time the radar beam scans across it, Pd is determined by factors that include the size of the antenna and the amount of power it radiates. A large antenna radiating at high power provides the best performance. For high quality information on moving targets the Pd must be very high.
The trajectory that a missile takes while attacking a moving target is dependent upon the movement of the target. A moving target can be an immediate threat to the missile launcher. The target must be promptly eliminated in order to preserve the launcher. In GOLIS systems, the problem is simpler because the target is not moving.
Intercept: Most systems can be used in different phases of ballistic missile flight, i.e., boost [73] (where surface or air-launched anti-aircraft missiles might also be effective because the ballistic missile is moving relatively slowly at low altitude), requiring proximity to the launch site and immediate response, mid-course/exo-atmospheric ...
On 24 February 2022, testers used IBCS to engage targets using various mixes of radars, interceptors, and fire control systems from the THAAD and Patriot systems. [53] For example, in a scenario where a THAAD system has to conserve its All-Up-Rounds, IBCS can calculate which targets are within the reach of its Patriot PAC-3 MSE interceptors ...

In MTI mode, moving targets are overlaid on a digital map. As well as large SAR aircraft such as the E-8 Joint Surveillance Target Attack Radar System (Joint STARS), whose AN/APY-3 radar has multiple modes including ground moving target indication, the US has highly classified radar satellites. Quill launched in 1964, was the first radar ...
The Germans were first to introduce PGMs in combat, with KG 100 deploying the 3,100 lb (1,400 kg) MCLOS-guidance Fritz X armored glide bomb, guided by the Kehl-Straßburg radio guidance system, to successfully attack the Italian battleship Roma in 1943, [20] and the similarly Kehl-Straßburg MCLOS-guided Henschel Hs 293 rocket-boosted glide bomb (also in use since 1943, but only against ...
Once the radar can "look down", it is subsequently desirable to "shoot down". Various weapons systems (including guns and missiles) are then employed against designated radar targets, either relying on the aircraft's radar employing the "look down" capability (as in semi-active radar homing) or the weapon's own active radar to resolve the indicated target (as in active radar homing).
