Abstract: 

In ultra-wideband (UWB) multistatic microwave breast cancer imaging, the long imaging time is an important issue. In this paper, a novel imaging method for multistatic UWB radar based microwave breast cancer imaging using sparse sampling has been proposed that significantly reduces the amount of data and imaging time. In this method, instead of measuring multistatic radar signals conventionally, just a few signals, by randomly choosing the transmitter and the receiver, are sufficient for obtaining reliable images even at high noise levels. Using simulations done, it is shown that sparser images can be obtained compared to the delay-and-sum (DAS) beam forming method using only a few received signals and a few time samples.
