Morava

The Morava M10 is an S-band primary surveillance radar (PSR) designed for air traffic control (ATC), compliant with ICAO and Eurocontrol requirements. Manufactured in Kunovice, Czech Republic, it operates between 2.7 and 2.9 GHz, with a peak power of 15 or 25 kW, and an instrumented range of 60 or 80 nautical miles. The radar employs a fully solid-state, highly modular, and fault-tolerant design, featuring redundant critical components such as dual motors and azimuth encoders for the turntable, and a doubled system for all important units to ensure continuous operation. Its antenna module, designed for tower mounting, incorporates a double-curvature parabolic reflector with two feedhorns, providing a cosecant-squared coverage diagram and dividing the receive pattern into lower and upper beams to mitigate ground clutter. The system utilizes alternating pulsewidths of 1 microsecond (µs) and 75 µs, with the longer pulse employing non-linear frequency modulation for digital pulse compression, and offers switchable linear and circular polarization to reduce weather clutter. The superheterodyne receiver with dual conversion and a high dynamic range feeds a digital signal processing system that uses moving target detection techniques to achieve a high probability of target detection with minimized false alarms, outputting data in ASTERIX or other specified formats for display on user-friendly Plan Position Indicator (PPI) scopes and Linux-based Control and Monitoring System (CMS) terminals.
