Abstract
Systems and methods for determining the position of a buoyancy element in a marine survey are described in which a passive reflecting material is disposed on the buoyancy element to enable a radar on the vessel to detect the position of the buoyancy element. The radar may emit a frequency modulated continuous wave or a sequence of frequency modulated or phase modulated sinusoidal waves.
