Solid-state S-band PSR MORAVA is intended for use as a source of information for air traffic management within terminal area.
MORAVA radar is developed in accordance with the latest requirements of ICAO and Eurocontrol
As modern ATC radar MORAVA consists of two main parts: solid- state primary radar, and built-in monopulse secondary radar. Both antennas are mounted on the same antenna base. PSR can be equipped with built-in MSSR supplied by NRPL Group or by a different supplier.
Wide coverage and high performance work under sever ground clutter conditions are provided by using a dual beam antenna, which is produced with the aid of extremely high-accuracy equipment.
Up-to-date solutions such as fail-soft solid-state transmitter, digital pulse generation and compression, adaptive digital signal and data processing, user-friendly radar data displaying system, remote control and monitoring system provide outstanding technical and performance capabilities of the MORAVA radar.
All equipment are located in a shelter with climatic system and uninterruptible power supply system. This solution simplifies the building process of the new radar site or upgrading the old one.
Low cost and high-level characteristics give the best price and quality ratio on the market.
The radar came to the ATC market in 2005. There are 10 radars delivered to customers for the beginning of 2010.
Digital radar signal processing system, coherent receiver and
transmitter provide detection quality improvement Solid-state
transmitter with air cooling
Linear and circle polarization decrease the influence of weather clutter
Digital generation and compression of signals provides higher stability
Processing of weather data
Adaptive regulation of parameters of the digital receiver decrease amount of false targets detections.
Built-in PSR and MSSR digital target extractor
Built-in tracking system
Tracker supports ASTERIX, AIRCAT 500 output data formats
Local and Remote control and monitoring system (L/RCMS)
Built-in test system for automatic monitoring of equipment parameters
Automatic reservation of radar's systems
System for analyzing, recording and replaying of the radar data
Operation of the radar without continuous staff presence
All software uses Linux operating system
One of the best price and quality ratio on the market
