Verfahren zur interferometrischen Radarmessung

摘要

The invention relates to a method for interferometrical radar measurement in a helicopter equipped with (heli radar). Said helicopter operates according to the ROSAR principle. Sensors of the ROSAR system are mounted on a rotating turnstile. Two coherent reception antennas with reception channels are assigned to one of said sensors. The path distance ( DELTA R) between the two distances (R+ DELTA R, R) and the point under consideration (P) is calculated from the wavelength ( lambda ) of the emitted radar signal and of the measured phase difference of the received echo of both coherent reception channels using a known method.
