Joint time-frequency signal processing scheme in forward scattering radar with a rotational transmitter

This paper explores the concept of a Forward Scattering Radar (FSR) system with a rotational transmitter for target detection and localization. Most of the research and development in FSR used a fixed dedicated transmitter; therefore, the detection of stationary and slow moving target is very diffic...
