RL-2000 PRIMARY SURVEILLANCE RADAR with possibility of collocation with ELDIS MSSR-1 radar RL-2000 is the latest generation of ELDIS primary surveillance radars for Terminal Approach Control Area. The radar meets or exceeds EUROCONTROL and ICAO recommendations and standards. The RL-2000 features fully solid-state highly modular configuration, fail-safe system and low life cycle costs. RL-2000 configuration includes weather channel for reporting of actual weather condition in TMA airspace. Basic RL-2000 configuration can be extended by monopulse surveillance secondary radar MSSR-1. This configuration extension is representing integrated system solution to TMA. radar control and monitoring system, to rapidly improve weather clutter rejection. Antenna system 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. The antenna system is shaping 2 double coverage cosec illumination pattern. The antenna system can operate in linear or circular polarization, which is adjustable via Transmitter Transmitter is modular air-cooled solid-state transmitter. The transmitter 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. Depending on customer's requirements, the transmitter unit is available in two power versions - 14 or 25 kW, composed of 16 respectively 32 independent modules and assuring minimum detectable range of 60 respectively 80 NM. Receiver Receiver is of superheterodyne type with double frequency down conversion. The high dynamic range is achieved by direct IF A/D conversion. The receiver has full digital automatic gain control, which is improving receiver stability and gain calibration. The receiver BITE diagnostics measures on-line receiver performance parameters, including noise figure.

Signal Processor The signal processor is based on 64-bit processors with high computing performance. Real time application software is written in “C” language, which provides efficient application solution for adaptive MTD processing. Signal processor performs the digital pulse compression for long pulses, the Doppler filtering through a bank of Doppler filters, adaptive CFAR filtering and the target detection and extraction. Adaptive CFAR filtering includes scan to scan filtration criterion evaluation and weather mapping. Extraction process involves using of filter amplitude for...
