Abstract :
Exact calibration of radar systems is an important problem to ensure the data reliability of the terrain and sea backscattering measurement. This technique calibrates L-band HH polarization airborne clutter measurement radar with active radar calibrator (ARC) on the ground. The effects of background clutter, airplane postures and GPS errors on system constant, time delay and antenna pattern are considered by means of design of RCS, signal extraction of ARC and a set of coordinate transforms
