The 9S35 Fire Dome provides a limited search and acquisition capability, a tracking capability and CW illumination for terminal guidance of the semi-active homing SAM seekers. It incorporates an IFF interrogator, optical tracker, datalink, and is powered by the TELAR's gas turbine generator.
Operating autonomously, the 9S35 will take 4 seconds to sweep a 120° sector, with an elevation of 6° to 7°. When cued to acquire and track, with will take 2 seconds to sweep a 10° x 7° az/elev solid angle. Average power output in pulsed tracking modes varies between 0.5 and 1 kiloWatt, with CW illumination at 2 kiloWatts. The search and monopulse angle tracking receivers are both rated at a Noise Figure of NF=10 dB. The range error is cited at 175 metres, the angular error at less than 1°. The radar can switch from standby mode to combat operation in twenty seconds.
