Zero-Doppler clutter( ZDC) caused by the surrounding environment of an outdoor measurement field is one of the major factors which degrade the accuracy of the target scattering signatures in wideband radar cross section measurement. A new technique for ZDC estimation based on maximal probability is proposed to effectively suppress background clutter and improve the measurement uncertainty. In this technique,an initial ZDC estimate for each frequency is obtained by sliding windowed average of the samples ove...
