Abstract :
Describes one technique for ultra wide band (UWB) time domain radar signal processing. Usually a radar is a narrow band system, but in this case transmitted signals are nanosecond short pulses without carrier which have a spectral content from 100 MHz to 1 GHz. Time domain backprojection is used to focus SAR images. The algorithm is tested with experimental data measured with an UWB prototype radar. The configuration of this radar is described and some UWB SAR images of canonical targets are presented
