A two dimensional short-range inclinometer radar, based on microwave i
nterferometry, is presented. It is able to detect the angles of deviat
ion of a reflecting plane with respect to a reference area with an acc
uracy greater than +/- 2 degrees over a dynamic range of +/- 25 degree
s. Theoretical and experimental results are presented for a metallic r
eflecting panel at 10 GHz.
