"Major threat confirmed:" Larson continued reporting, his speed steady but clear,
"Signal Alpha: Center frequency approximately 5.4 GHz (C-band), pulse repetition frequency (PRF) approximately 1500 Hz, pulse width approximately 0.8 microseconds. Signal characteristics match Russia's 9S18M1 'Shield' (NATO codename 'Tube Arm') three-coordinate search radar with a high matching degree of 94%. This is the eye of the 'Tor M2' air defense missile system. It is currently in slow rotating search mode, with a scan cycle of about 6 seconds, likely in early warning status."
"Signal Bravo: Center frequency approximately 16.2 GHz (Ku-band), high pulse repetition frequency, continuous wave/pulse Doppler mixed mode, scanning method is fast fan scan. Characteristics match 'Armour S1' gun-missile system's 1RS2-1E phased array fire control radar with a matching degree of 91%. It is executing 360-degree panorama search, with fast reaction speed."
