Abstract

In the formation of range-Doppler images, transient interference can result in Doppler-streak artifacts. These Doppler-streaks hinder the utility of the range-Doppler image and may obscure moving targets of interest. This paper describes a method for pre-processing the IQ data to substantially attenuate Doppler streaks in the subsequently formed range-Doppler images. The method consists of decomposing the IQ data for each range bin into the sum of an oscillatory component and a transient component.
