ABSTRACT:
It is proposed in connection with a method for the interferometric radar measurement in conjunction with a helicopter operating in accordance with the ROSAR principle (Heli-Radar) that two coherent receiving antennas with receiving channels are associated with a transmitter of the ROSAR-system mounted on the revolving rotary cross; and that the difference (ΔR) between the two distances (R+ΔR, R) from the measured impact point P are calculated, in the manner known per se, based on the wavelength λ of the emitted radar signal and the measured phase difference of the receiving echo of the two coherent receive channels.
