Advanced Signal Processing for Ultra-Wideband Synthetic Aperture Radar (SAR)

Ultra-wideband SAR in the VHF and UHF bands is commonly used for foliage-penetration applications, i.e. stand-off detection of objects concealed in forest. The currently main limiting factor is the strong backscattering obtained from dense forests. The talk will discuss possibilities to improve detection performance. One possibility which will be discussed is to improve resolution by increasing the integration angle. Another possibility which will be discussed is to use bistatic scattering geometries. The challenges for the signal processing will be outlined and possible solutions described.
