Radar-Based Classification of Unmanned Aerial Vehicles (UAVs) Carrying Payloads

Unmanned Aerial Vehicles (UAVs), commonly referred to as drones have gained increasing popularity with current technological breakthroughs. Recent reports indicate the number of registered drones in the United States have crossed 850,000 and is expected to increase multi-fold over the coming years. The widespread applications of drones include...

Radar Doppler Polarimetry of Wind Turbines using the S-band PARSAX radar

Due to the necessity of more sources of renewable wind generated energy, the number of wind turbines in the Netherlands has grown in the past. Unfortunately, big sizes and movements of the blades negatively impact ground-based Doppler radars in the form of Doppler clutter. Such clutter leads to a downgrade of the surveillance radar performance...

Estimation and assessment of differential and specific differential phase with the IDRA X-band Doppler polarimetric radar

The specific differential phase (Kdp) is a polarimetric radar observable which can be advantageous for rain rate estimation as it is not affected by absolute calibration errors and resistive to hail contamination. Its estimation, starting from the differential phase (?dp) consists of many processing steps and considerations which are more...
