RW-31 “Bożena” (from Radiolokacyjna - Wysokościomierz, Bożena is a Slavic girl's name) was an height finding radar operating in S-band. The radar was coupled with a 2D surveillance radar and could report height to the radar's target. However, it could also operate in an around-view or sector mode to detect low-flying targets and feed the echo signals to the surveillance radar's display unit.
The antenna, which nodded with a hydraulic drive, nodded four times per minute. The radar electronics were of mixed tube and semiconductor design. The radar used two magnetron transmitters. Relocation to a new site could be accomplished with 3 TATRA-148s and two trailers.
It was produced at the Warsaw RAWAR radio factory for the Polish Air Defense from 1972. It was the predecessor of the NUR-41.
