We can conclude that the Elefant radars were experimental, conceived in several respects in imitation of CH, and intended for several purposes - but inspired by the same thinking that led to KH; in other words a recognition that the German early warning radar was potentially severely compromised by Allied countermeasures. The several purposes were (i) air defense (monostatic) in the same way as CH but particularly when the conventional radars were jammed or otherwise unusable, and there are several pieces of evidence that it did this quite effectively; (ii) tracking of V-2 rockets; this seems quite plausible, although there is not a great deal of evidence of the effectiveness; and (iii) for bistatic experiments, either using CH transmissions (noncooperative, in the same way as KH) or transmissions from other Elefants. The radars demonstrated some remarkable examples of engineering.
