REL-2

REL-2 is a further development of the Type 518 naval radar and the land-based REL-1. It uses the parabolic reflector of the REL-1 with dimensions of 15.5 m wide and 8 m high. The antenna provides a cosecant squared pattern.

The REL-2 was later replaced by the lighter and more successful against stealth aircraft Type 517M radar.
