Advanced S-Band Solid-State Primary Surveillance Radar Morava 10

PSR Morava 10 is a latest generation primary surveillance radar designed and manufactured by NRPL under ISO 9001:2008 certified quality system. The radar is intended for ATC surveillance within airport terminal area. PSR Morava 10 extended range feature allows using it for en-route application as well. PSR Morava 10 is a field proven PSR system installed at numerous sites worldwide. The system can be flexibly adapted for operation in different environment including wind-farm fields, mountains, and coastal areas. PSR Morava 10 is a very compact and energy efficient solution which reduces demands to installation sites and non-radar auxiliary equipment. PSR Morava 10 fully meets and often surpasses requirements and recommendations of ICAO and EUROCONTROL standards. PSR Morava 10 characteristics were proven by civil aviation authorities of Lithuania, UK, Kazakhstan, South Korea and Czech Republic. PSR Morava 10 is a cost-effective and low maintenance cost solution featuring fully solid-state, highly modular and reliable design with integrated comprehensive BITE system. The radar offers an improved system stability, effective clutter attenuation and elimination of false targets with maintained high probability of target detection up to a distance of 120 NM. High-precise dual-beam antenna ensures reliable coverage within the area and high performance of the radar even under severe ground clutter conditions. Advanced beam switching and combining algorithms mitigate dynamic high-speed clutter such as road traffic, wind turbines and trains. PSR Morava 10 also includes an independent high-resolution weather channel providing precise information on weather conditions (US-NWS 6 level). PSR Morava 10 is very flexible and can be easily integrated with MSSR, ADS-B or MLAT systems. In this case, a common CMS will display status and performance parameters of all systems simultaneously and PPI screen will display combined targets processed by advanced built-in tracking system.
