Micro-Doppler signatures can be a useful source of information for target classification. The exploitation of these signatures is difficult because of the presence of stationary target and noise that enters the receiver antenna beam. Of particular interest in this work is micro-Doppler signatures of helicopters rotor blades observed from systems with relatively large wavelength and illuminators of...
The presence of wind farms rose significant problems in the radar community, principally for meteorological and air traffic control radar. The presence of active wind turbines can affect also radar imaging systems that monitor ground and sea areas where windmills are often present. The blade motion introduces Doppler effect on the returned echoes to the SAR platform that can introduce undesirable...
