DRBJ 11 (designated by its manufacturer as TRS 3501) is operating in the S-Band air search and target designation radar.
The antenna is a rotating planar phased array scanning electronically in both bearing and elevation. The circular aperture has a diameter of 3.0 m and consists of 1 000 … 1 500 spiral shaped radiating elements. Each radiating element has its own processor-controlled module with a PIN-diode phase shifter.
