RL-2000/L Primary Surveillance Radar


RL-2000/L is latest generation of ELDIS primary surveillance radars for En-Route Airspace and Major Terminal Areas. The RL-2000/L design is benefiting from the long time experience on several civilian and military radar types. The radar meets or exceeds ICAO and EUROCONTROL recommendations and standards. The RL-2000/L features fully solid-state highly modular configuration, fail-safe system and low life cycle cost.
This radar provides enhanced system stability and powerful clutter suppression to allow no false reports while maintaining excellent target detection up to 240 NM, including enhanced performance for target accuracy and resolution.
Basic RL-2000/L configuration can be extended by monopulse surveillance secondary radar MSSR-1.
The system configuration includes operational and stand by channels with automatic switchover processed by system Level. The data output format is using standardized ASTERIX data format, but as an option other data formats can be used. The maintenance and repair actions are reduced to minimum and sophisticated remote control and monitoring system allows an unattended system operation.

The antenna system is shaping double coverage cosec2 illumination pattern. The antenna system can operate in linear or circular polarization, which is adjustable via radar control and monitoring system, to rapidly improve weather clutter rejection.

Transmitter is modular air-cooled solid-state transmitter. The transmitter is composed of 32 independent modules and is operating in full frequency range with frequency diversity for short pulse and long pulse transmission. Design is fault tolerant with low voltage power supply, which allows continuous operation during maintenance.

RF generator is digital waveform synthesizer, which provides optimum number of short and long pulses over coverage period. Short pulse and long pulse waveforms are generated fully digitally. Pulse repetition interval is changed by two up to four bursts per dwell to minimize blind speed losses.

Receiver is superheterodyne type with double frequency down conversion. Direct A/D IF conversion with low jitter clock source and digital Amplitude Phase Detector provides a high dynamic I and Q video without DC drifts and I/Q inaccuracies. Noise sensors allows automatic gain control feedback to IF amplifier. This design avoids any needs of periodic adjustment. The receiver BITE is testing on-line receiver performance parameters, including noise figure.

Signal processor performs digital pulse compression for long pulses, Doppler filtering through an eight-filter and adaptive CFAR filter bank, target detection and extraction. The number of Doppler processed pulses and filter coefficients are adaptively based on actual CPI burst length. CFAR filters adaptivity is based on high resolution 32 scan history clutter estimation maps allowing superclutter visibility capability good intraclutter visibility and flat speed response with no blind speed operation in clear. Extraction process involves using of echo amplitude and doppler speed information for range/azimuth target coordinates evaluation with high accuracy and resolution capability.

Each system equipment or unit is fitted with independent BITE to perform performance monitoring and automatic system reconfiguration at system Level. CMS has two parts – local control and monitoring system (LCMS) and remote control and monitoring system (RCMS). LCMS is located on radar site. RCMS can be located on technical room of airport tower, etc.
Both systems are communicating via communication line, which can be represented for example by LAN via optic fibre cable, and have same functional capabilities. CMS monitors continuously radar status and performance and allows to the maintainer remotely control and adjust radar configuration and parameters. CMS incorporates user-friendly graphical interface, which is used for data and status presentation.
