Isolating target returns through foliage

Summary form only given. Foliage penetration synthetic aperture radar imaging requires large wavelength (VHF/UHF) as compared with standard SAR working in the X-band or at even higher frequencies. As a consequence, the identification of targets is difficult, since the low resolution essentially tends to eliminate the difference between the returns of different target features. The purpose of this work is to analyse the scattering characteristics of generic targets as well as applying inverse scattering algorithms to image point targets under foliage. The authors compare different methods and discuss the advantage of each method given a particular type of prior information. Special emphasis is given to the discrimination of different types of specular reflections.
