A new method to separate ground clutter and atmospheric reflectionsin the case of similar Doppler velocities

This paper introduces a new ground clutter suppression technique which preserves weather echoes. This clutter suppression method uses both statistical and polarimetric properties of the target and clutter. This technique is intended for use in atmospheric studies for weather echoes the spectral properties of which do not differ much from those of ground clutter. This technique can be applied both to the total signal or to its separate Doppler frequency components     

Two-switch forward soft-switching PWM DC-DC power converter

A novel prototype is presented of a two-switch forward soft-switching PWM DC-DC power converter with reduced switching and conduction power losses, which can operate under two soft commutations of zero voltage and zero current of full bridge circuit topology
