In this paper, we analyze the characteristics of the radio frequency interference (RFI) data in the time-frequency domain. A matching pursuit (MP) method is proposed for RFI suppression in ultra-wideband synthetic aperture radar (UWB-SAR) system. The algorithm decomposes the SAR echo over a modified Gabor dictionary to remove the significant RFI. The performance for the algorithm is investigated by...
Portable radar was designed for through wall detection of live being and tracking. A combined sampling oscilloscope was used as a receiver and a short pulse generator as a transmitter.
Recent critical instances have demonstrated the demand for an effective way of detecting and classifying small Unmanned Aerial Vehicles (UAVs) as they pose a serious threat in civil security. We present results of radar measurements with a one channel continuous wave system at Ka band aiming at classifying UAVs through a detailed micro-Doppler analysis. High-sensitivity measurements of different UAVs...
Radar sensors become typical components for automotive driver assistance systems and autonomous driving. The widespread use of this sensor type leads to an increasing risk of unwanted interferences. Those interferences can severely degrade the detection performance and cause sensor blindness. To overcome this problem, this paper describes a method to estimate and remove interfering signals in data...
