The 2D Surveillance Radar P-180U

The 2D Surveillance Radar P-180U is a new product from the “UKROBORONSERVICE” SC. This product implements all of the modern design methods combined with the longstanding experience of the company.

Among its main features are:

  • full coherence is implemented, due to the significant improvements in radar performance;
  • a wide range of narrow and broadband probing signals enabling radar adaptation to various combat conditions; 
  • digital signal processing, including matched filtration, clutter and active jamming suppression, target detection and coordinate measuring, target tracking and data distribution to consumers; 
  • practically approved reliable software developed by Aerotechnica with a user-friendly interface; 
  • only COTS components are used from renowned suppliers - this coupled with quality system approval guarantees the high level of reliability.

Equipment structure

Two working places are included in the Radar structure:

  • Operator’s workstation and remote workstation with multi-windows
  • color graphics interface.

Distance between remote workstation and radar depends on communication channel. Remote workstation provides radar remote control;
Data transfer is carried out through the standard detached tone frequency channel with pass bend of 0,3-3,4 kHz (physical communication line, radio-relay communication channel, troposphere communication channel, very high frequency waves- communication channel, satellite communication channel).

The following equipment are included in the structure of the updated radar assembly set equipment:

  • Solid-state receiver, included;
  • Digital processing and synchronization unit (including MTI system) with characteristics as follows;
  • Computerized air conditioning control system;
  • Power supply and lighting distribution unit;
  • Fire-fighting system;
  • Operation-command communication system;
  • Switchboard.

Advantages of P-180U:

  • large number of probing signals, ability to choose the best depending on the air situation, jamming and combat conditions. For instance, narrow band for near field (good detection against clutter background), broadband for long range (large detection range, especially for smaller size targets); 
  • parameters of probing signal - working frequency, modulation type, waveform - are all reconfigurable; 
  • reconfiguration of signal parameters can be carried out via program or randomly (plus, reconfiguration of probing signal parameters does not affect the quality of clutter suppression); 
  • increase of signal to noise ratio due to matched filtration of received signals, increase of detection range and accuracy;
  • significant (up to 100dB) increase of a dynamic range resulting in high jamming immunity and suppression of clutter and weather formations;
  • efficient algorithms for clutter suppression with wind speed compensation;
  • automatic combining of amplitude and coherent channels which decreases signal loss and increases detection range and accuracy;
  • implemented functions of a radar extractor for post-detection signal processing (detection, location measuring, plots generation, clutter map, scan-to-scan processing, stabilization of false target generation, processing of identification signals, data distribution to consumers);
  • low power consumption;
  • user-friendly design for easy operation (maintenance) of radar;
  • efficient monitoring system of all components.

Dejamming capabilities

A range of hardware and software solutions are implemented in the P-180U which enables suppression of the following kinds of jamming:

  • nonsynchronous and chaotic pulse noise;
  • response pulse noise;
  • active noise jamming.

Suppression of pulse noise is implemented in software and enables full suppression of pulse noise.

For suppression of active noise jamming including interfering from TV centres, radios and other sources the following steps are implemented:

  • automatic monitoring of active noise conditions and automatic adaptive working frequency hopping 0.2 MHz discreet;
  • high dynamic range of signal processing system (of the receiver and digital signal processing unit) - 105dB;
  • extra expansion of dynamic range (by 30 dB) through automatic gain control;
  • 4-channel dejammer of active jamming is offered as an option, providing jamming suppression of 32 dB (at SNR of 40 dB).

Options:

  1. 4-channel digital dejammer.
  2. Remote automated working position.
  3. Data recording system.
  4. Simulation system.

Radar design

The design of the radar can be changed in accordance with customer requirements.

The radar equipment can be placed on ZIL, KrAZ, KAMAZ vehicle chassis (and similar) or in a fixed-position shelter. As an option, this equipment can be installed in a modified hardware compartment of the P-18 radar.

A partition is inserted in this configuration in order to separate hardware and operating personnel. The advantage of this option is that it lowers the price of the radar.

All the equipment is installed in one compartment. Hardware is mounted on the walls on specially designed frames providing easy access to all composite elements and easy maintenance.

There are operator working positions and remote working position with seats for operating personnel.

The mast antenna assembly is placed on a separate vehicle (trailer). The power supply system is placed on a separate trailer(s) or on the antenna trailer. Power from industrial mains can also be arranged.
