Ground clutter cancellation in incoherent radars: solutions for EISCAT Svalbard radar [PDF]
Annales Geophysicae, 2000 Incoherent scatter radars measure ionosphere parameters using modified Thomson scatter from free electrons in the target (see e.g. Hagfors, 1997). The integrated cross section of the ionospheric scatterers is extremely small and the measurements can ...

Microwave detection of buried mines using non-contact, synthetic near-field focusing [PDF]
, 2001 Existing ground penetrating radars (GPR) are limited in their 3-D resolution. For the detection of buried land-mines, their performance is also seriously restricted by `clutter'. Previous work by the authors has concentrated on removing these limitations
