Item Open Access Experimental analysis of multistatic multiband radar signatures of wind turbines(2016-05-23) Balleri, Alessio; Fioranelli, F.; Ritchie, M.; Griffiths, H. D.This study presents the analysis of recent experimental data acquired using two radar systems at S-band and X-band to measure simultaneous monostatic and bistatic signatures of operational wind turbines near Shrivenham, UK. Bistatic and multistatic radars are a potential approach to mitigate the adverse effects of wind farm clutter on the performance of radar systems, which is a well-known problem for air traffic control and air defence radar. This analysis compares the simultaneous monostatic and bistatic micro-Doppler signatures of two operational turbines and investigates the key differences at bistatic angles up to 23°. The variations of the signature with different polarisations, namely vertical transmitted and vertical received and horizontal transmitted and horizontal received, are also discussed.Item Open Access Experimental analysis of multistatic wind turbine radar clutter statistics(Institution of Engineering and Technology (IET), 2023-02-01) Fioranelli, F.; Ritchie, M.; Balleri, Alessio; Griffiths, H. D.This Letter presents preliminary results of the analysis of amplitude statistics of wind turbine clutter as extracted from multistatic radar data. It is shown that the T-location-scale distribution provides good fitting of the experimental data, and that there are combinations of bistatic angle and polarisations where the bistatic clutter has more favourable statistics for target detection than the simultaneous monostatic clutter.
