57U6 “Periskop-VM” was operating in L-Band coherent 2-D surveillance radar designed for detecting low flying aircraft and cruise missiles.
These radars were therefore usually installed on a high tower or on the peak of a mountain. They were completely remote controlled. There was a version for a fixed installation and a mobile version on a flat trailer. The radar already used digital filters in the radar signal processing and automatic monitoring of its technical performance.
The radar 5U75 “Periscope-V” was put into service in 1978, its improved version 57U6 “Periscope-VM” about 1984. These radars were installed in the mountains along the southern borders of the former Soviet Union. After the collapse of the Soviet Union these sites were mostly abandoned and destroyed by looters.
