Description
This radar was developed from the Flat Face A. It is associated with SA-2 Guideline, SA-3 Goa, SA-6 Gainful, and SA-8 Gecko SAM systems. It is also designated the 1RL134. The P-19 is truck-mounted on a 6 x 6 chassis and employs an antenna array with two elliptical reflectors mounted one above the other. Like the P-15, it uses the 1L22 Parol IFF equipment. Digital plot processing has been fitted.

Variants
Flat Face A (Russian P-15)
This variant is associated with SA-2 Guideline and SA-3 Goa (Russian S-125 Neva) SAM systems. Operates in C-band. It is also designated the 1RL13.
Bharat Electronics P-19 upgrade
This modernization includes a new digital signal processor providing moving target indication with staggered pulse repetition frequency; a new solid-state low-noise amplifier; color raster scan display; IFF provisions; and built-in test equipment.
ELSYS P-19 upgrade
This version from Ukrainian firm ELSYS includes an MSHB-19 low-noise microwave amplifier, which features a limiter that reportedly has an operating frequency of 700 to 1,000 MHz; a gain of 26 to 32 dB; a 3 dB noise figure; and a maximum allowable input pulsed power value of 3,000 W.
Retia RLP-19/IFF P-19 upgrade
This modernization includes an AN/TPX-56 IFF interrogator, updated communications, digital processing, new display console, Doppler filtering, planar IFF antenna and built-in test equipment.
KB Radar P-15R
This is an upgrade to the P-15 radar developed by KB Radar in Belarus. The modernization includes a MAZ truck chassis, or other chassis as requested by the customer; standard shelter; standard top and bottom antennas; upgraded bottom antenna phase switch; standard rotary support mechanism with slip rings; and an upgraded digital azimuth meter.
Ukroboronservice P-190U
This is a P-19 radar upgrade from Ukroboronservice in Ukraine. It features automated workstations; improved radar performance; wide range of narrow and broadband probing signals enabling the radar to adapt to various combat environments; digital signal processing, including matched filtration; clutter and active jamming suppression; target detection and coordinate measuring; target tracking; and data distribution. New software features a user-friendly interface.
DefTech P-19 upgrade
This is a modernization offered by DefTech Global in the United Arab Emirates. It features an all solid-state design that enhances all combat capabilities and reduces maintenance. New equipment includes a solid-state transmitter; solid-state receiver; and digital signal processing. Optional gear includes a four-channel dejammer; height-finder control software and equipment; software for guiding fighter jets; software for targeting air defense systems; and equipment for documentation.
Kasta-2E (39N6E/Casta 2E/Flat Face E)
This is an all solid-state variant of the rugged and effective Flat Face. Digital moving target indication (MTI) improves countermeasure resistance. Wide-band reflections from clouds are screened out by a special filter. To combat jamming, the radar employs automatic or manual selection of any one of 10 carrier frequencies, phase modulation and constant false-alarm rate (CFAR) processing, among other techniques. "Flicker" radiation, where the radar is turned on and off intermittently, reduces its vulnerability to anti-radar missiles. The radar is optimized to detect low-flying targets in heavy surface and weather clutter environments.
P15M2 (NATO Squat Eye)
This variant operates in the C-band and has a single antenna on a tethered latticework mast. See separate record for more information.
