Ground-based mobile surveillance radar P-19MA/P-190U

P-19_general    

Ground-based mobile UHF low, medium and high altitude surveillance radar P-190U is offered as the modernized follow-on to its prototype, the analogue P-19.

P-190U radar features:

  • maximum use of COTS components;
  • stable, fail-soft, modular solid-state transmitter;
  • built-in test equipment;
  • no special adjustments required during operation;
  • largely simplified maintenance;
  • engineered for minimum cost of ownership.

As a result of modernization the radar’s detection performance is efficiently improved. Modernized radar features automatic tracking capability as well as data receiving from other radar sensors. Data can be exchanged over a variety of communication channels in approved format. 

Depth of modernization:

The radar’s equipment cabin is fully modernized. Frequency range is preserved at 825-890 MHZ, however the number of working frequencies is increased from 3 to 160, 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 to partial performance degradation.

Antenna system features new “upper beam – lower beam” fast electronic switch that replaced slow mechanical unit. Such upgrade allows for new modes of operation – for instance, transperiod beam switching provides full scanning of airspace in one rotation of the antenna. Also, new asynchronous motor drive assembly is installed controlled by frequency inverter. 

Power supply system is transferred from 400 Hz frequency to industrial 50 Hz.

P-190U radar remains a two-dimensional system and is used to find azimuth and range. Altitude can be obtained by interfacing modernized height-finding radars. 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 workstation. Both workstations are installed in the equipment cabin in standard configuration.

As an option, ground interrogator can be controlled in auto- and semiautomatic modes with assigning aircraft state identification status.

All air situation is automatically recorded with playback capability in passive and interactive modes. 

P-190U radar features efficient protection against pulse interference and active jamming. Level of interference is continuously monitored and graphically represented to the operator. Jamming protection is achieved through expansion of the dynamic range of the signal processor and capability of electronic frequency agility. Passive interference is rejected through digital adaptive MTI and generation of clutter map. 

P-190U radar is positioned on two vehicles. Power generators are accommodated in the antenna-mast assembly vehicle.

       

Modernized P-19MA radar is adopted by MoD of Ukraine for its Armed Forces.
