General Information Purpose of IVTs-M1(M2) The IVTs-Ì1(M2) (ÈÂÖ-Ì1(Ì2)) aerial target simulator is designated for training of surface-to-air missile (SAM) system combat crews at the level of the regiment, division and army corps in Air Defense, Air Force troops and Navy, consisting of firing at simulated modern and future-generation air targets, as well as for debugging and testing the newly-developed air defense systems. The IVTs-Ì1(M2) has been developed by the Scientific and Industrial Unitary Enterprise «Tetraedr». An IVTs-Ì1(M2) is installed in lieu of the standard 9Ì28D (9Ì22U) rocket warhead of the «Grad» salvo system, and provides the required radar cross section in the radar band (IVTs-Ì1,IVTs-M2) and irradiation in the optical wave band (IVTs-M2) (photo 1, 2).

The modification «M1» simulates aerial targets only in the 2 - 4 cm radar band width. The modification «M2» of aerial target simulator is the second one in the family of simulators developed and manufactured by the UE «Tetraedr». An IVTs-M2 makes it possible to simulate aerial 8 both in the 2 - 4 cm radar band width and in the optical range. targets The «M3» of aerial target simulator modification shall be equipped with an active jammer, which will provide jamming in the 2 - 4 cm wave band. The main performance characteristics of IVTs-M1(M2) are presented in Fig.1.
