---------------------------------------------------------------
The P-18 radar is a 2D mobile early warning radar operating in VHF band. Main P-18 radar advantages are ability to detect stealth targets and inability of anti-radiation missiles seeker to detect such radar (VHF antenna does not fit into missile body).
Despite of highly reliable simple mechanical construction, original radar cannot fulfill today's requirements. Original radar signal processing is not able to detect and track targets inside heavy jammed or cluttered regions. Manual data readout does not fulfill requirements on target processing capacity and accuracy.
Proposed radar modernization suppresses aforesaid imperfections. Modernized radar provides significant performance improvement.
Radar Modernization Benefits
- New design of electronics architecture
- Tailored solution according to user needs
- Improving the radar system performance
- Application of the latest digital and microwave technologies
- Increased resistance to the electronic warfare (ECCM)
- Introduction of digital radar data output interfaces
- Removing outdated and inaccessible components
- Increase reliability, lifetime and spare parts availability
- Improved diagnostics and remote control
- Integration of standard identification system friend or foe
- Reduced operating costs
The radar modernization can be carried out either at RETIA, a.s. plant or to avoid radar transport at user's overhaul enterprises. An overall support is guaranteed for production as well as service phases.
Suggested radar modernization can be gradually structured depending on user requirements, military authority policy, budget priority, etc.
P-18 Radar Modernization includes
- Fully coherent all-solid state radar transmitter
- Receiver with direct digitizing of signal at IF
- Digital Signal Processor with MTD processing
- Data Processor with automatic target coordinates extraction
- Local console LMCC (for analogue and synthetic target data and comprehensive monitoring and control information)
- Standard radar console SRCC
- Radar data recording equipment
- Auxiliary ECCM channel - ECCM antenna array and receiver
- Auxiliary GPS channel - GPS antenna and receiver
- BITE (online and offline)
Option
- IFF system integration - IFF interrogator and flat array antenna
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
