Ground-based long-range UHF band surveillance radar P-19MA (P-190U)

Ground-based long-range UHF band surveillance radar P-19MA (P-190U) is offered as the upgraded follow- on to its prototype, the analogue P-19.

As a result of upgrade the radar detection performance is efficiently improved. P-19MA features automatic tracking capability as well as acquisition of data from other surveillance radars and height- finders. Data can be exchanged over provided communication channels in approved format.

Features of P-19MA (P-190U)

  • UHF band;
  • Maximum use of COTS components;
  • Stable, fail-soft, modular solid-state transmitter and receiver;
  • Built-in test equipment;
  • No special adjustments required during operation;
  • Largely simplified maintenance;
  • Engineered for minimum cost of ownership.

Depth of upgrade

  • Radar equipment cabin The radar equipment cabin is fully upgraded.
  • Frequency range Frequency range is expanded to 825 – 890 MHz, the capability of instantaneous electronic frequency agility is added. Radar transmitter and receiver feature solid-state components only. The transmitter has a modular design and provides “soft-failure” redundancy: failure of individual module leads only to partial reduction in power. Antenna-mast assembly is equipped with a new 50 Hz asynchronous motor controlled by a variable-frequency drive as well as new antenna tilt sensor.
  • Two-dimensional system P-19MA remains a two-dimensional system and is used to find azimuth and range. Altitude can be obtained by interfacing with upgraded height-finding radars, in this case radar and height-finders operate as a 3D radar complex. Parameters of transmitted signal as well as parameters of signal processing after reception can be set at the operator workstation, secondary processing and tracking are performed at the remote work-station. Both workstations are installed in the equipment cabin in standard configuration.
  • Additional option As an option, ground interrogator can be controlled from the radar with the assignment of aircraft state identification status.
  • Efficient protection P-19MA radar features efficient protection against pulse interference and active jamming. The operator workstation graphically presents noise to the operator allowing for visual assessment of jamming and interference at given frequency and bearing of a jammer. Jamming protection is achieved through expansion of the dynamic range of the signal processor and capability of quick electronic frequency shifting. Passive interference is rejected through digital MTI and generation of adaptive clutter map.
  • Chassis design options Various chassis configurations are available. The number of vehicles in configuration on “KrAZ” (or other) chassis is 2.

Подвижный радиовысотомер ПРВ-16МА предназначен для измерения координат целей (азимут, наклонная дальность, угол места) по данным целеуказаний РЛС или КСА, с которыми сопрягается высотомер. Высотомер ПРВ-16МА сопрягается с радиолокационными станциями П-18МА, MARS-L, П-19МА и комплексами средств автоматизации.
