Abstract
Researchers at the Army Research Laboratory (ARL) have recently developed an iterative technique for improving image quality in ultrawideband (UWB) radar systems. This technique, dubbed "recursive sidelobe minimization" (RSM), has been applied extensively to data sets in which no constraints have been placed on the amount of transmitted bandwidth. That is, no frequency notching was required prior to transmission of the waveform. In this paper we describe an extension of the earlier RSM technique designed to reduce the artifacts introduced by frequency notching. We include results obtained applying the technique to both simulated and measured data.
