P-18 (Spoon Rest)
The P-18 radar is a 2D mobile long-range early warning radar operating in VHF frequency band. VHF frequency band brings two main advantages, ability to detect stealth targets and inability of anti-radiation missiles seeker to detect such radar (VHF antenna with sufficient angular resolution simply does not fit into missile body).
Despite of highly reliable simple mechanical construction, original radar that is equipped with outdated electronics cannot fulfill today's requirements, mainly in point of operation automation and radar networking capability. The following modernization is necessary to overcome the aforementioned deficiencies:
- Radar signal processing
- Up-to-date display
- Radar data output
- Up-to-date IFF system
- Improvement of system reliability
Original radar signal processing is not able to detect and track targets on heavy jammed or cluttered regions. Manual data readout (extraction) does not fulfill today's requirements on target processing capacity and accuracy.
Modernized radar eliminates aforesaid imperfections providing significant performance improvement, especially in EA (ECM) environment, increases reliability and extends radar lifetime.
Proposed modernization includes:
- Fully coherent all-solid state radar transmitter
- Transmitted waveform generator (Exciter)
- Receiver with direct digitizing of signal at RF
- Digital Signal Processor with MTD processing
- Data Processor with automatic target coordinates extraction
- Local console LMCC
- Standard radar console SRCC
- IFF interrogator with flat array antenna
- Auxiliary ECCM channel - ECCM antenna array and receiver
- Auxiliary GPS channel - GPS antenna and receiver
- BITE (online and offline)
P-19 (Flat Face)
The P-19 radar is highly mobile early warning system designed for low level and “Stealth” targets detection and tracking. The original obsolete electronics however makes impossible to utilize its potential technical and tactical capabilities.
Offered P-19 radar modernization overcomes both technical and technological barriers of the original system. The signal processing digitization enables automatic target detection, extraction and data transfer to a radar network or linked command and control centre. The installation of the IFF interrogator (Mark XII NATO standard) and a local monitoring and control console completes basic range of the modernization.
To achieve full coherent system the P-19 modernization can be extended by a solid-state transmittertransmitter
P-37 (Bar Lock)
P-37 surveillance radars are still in service in many countries. Obsolete original electronic blocks and inaccessibility of same components cause a number of problems. Some characteristics of this robust, environmentally resistant and reliable system make foundation for radar lifetime extension however radar modernization is necessary for more P-37 radar utilization.
Main radar modernization objectives
- Improve radar performance
- Introduce modern digital and microwave radar technology
- Introduce digital data output interface
- Increase ECCM capability
- Remove obsolete inaccessible components
- Improve diagnostics and remote control
- Increasing of reliability and lifetime
RETIA variant / total P-37 radar modernization consists especially of
- New transmitter
- New RF block
- Up-to-date data processor unit with extractor
- Standard radar console SRCC and Local monitoring console LMCC
- Standard Digital Output into Superior Command Centers
- BITE diagnostics
PRV-17 (Odd Pair)
Original PRV-17 radar heightfinder is analogous system with manual antenna azimuth turning control only.
Modernization improves system by
- Solid-state RF amplifiers with STC
- Automatic digital 3D extractor
- SW algorithms for target coordinates determination
- Automatic remote (/local) control of antenna azimuth position
- Radar data output into multi-radar network
- ON-LINE and OFF-LINE diagnostics of new units
Remote antenna control enables sectoral searching and/or automatic height measuring up to 12 selected targets simultaneously. PRV-17 Interconnection with modernized surveillance radar (P-37, P-18, etc) carries out 3D system for target detection and tracking.
ST-68 (Tin Shield)
The ST-68U is mobile 3-D medium range air surveillance and missile control radar. Original, fully coherent system is not equipped with suitable data output to standard C3I centers suitable standard IFF system is missing as well.
The system is after modernization extended about:
- Up-to-date IFF interrogator
- Digital interface for narrow band radar data output
- New local and remote monitoring and control consoles SRCC and LMCC iaw EUROCONTROL recommendation
- New low noise RF amplifiers in all channels of primary radar
Modernized data processor enables all automatic target tracking. Centralized diagnostics and control can be performed by means of local or remote monitoring and control console. Modernization has achieved
- All automatic radar operation
- Identification compatibility with NATO standard (IFF Mark XII)
- Networking capability
- Increased performance, reliability and availability
- Longer lifetime, lower operational costs
