The s-193 radar altimeter experiment
WebbAlthough similar in form and function, the purpose of a remote-sensing altimeter is different, since usually it is mounted on a spacecraft whose orbital height is known. Remote-sensing altimeters are designed to retrieve certain geophysical parameters about the surface from the timing and shape of the radar reflections (waveforms). WebbWith these examples illustrating the developed concepts, algorithms, and approaches -- the book helps radar engineers develop tracking solutions when observations are non-linear ... namely the waves that propagate in vicinity of the earth's surface (e.g., guided by that interface), without involvement of any atmospheric effects ...
