Abstract

In conjunction with an arrangement for the interferometric radar measurement in connection with a radar system operating according to the ROSAR principle, comprising one coherent transmitting antenna and two coherent receiving antennas and their receiving channels, in connection with which the difference in the path between the two distances of the antennas and the measured points of impact is calculated by the wavelength λ of the emitted radar signal and the measured phase difference of the receiving echo of the two coherent receiving channels, it is proposed that the interferometric ROSAR system is integrated in or on a rotating device and positioned in such a way that each relevant area of the field to be measured can be detected.

Dependent claims

An arrangement for interferometric radar measurement having a plurality of ROSAR systems linked together, each ROSAR system comprising:

at least one coherent transmitting antenna for emitting a radar signal;
at least two coherent receiving antennas that receive a radar signal;
at least two receiving channels, one disposed on each receiving antenna;
and
a rotating device having a rotating arm upon which said at least one coherent transmitting antenna and said at least two coherent receiving antennas are integrated;
wherein a difference in radar signal path distance between said at least two coherent receiving antennas and measured points of impact is calculated using a wavelength λ of said emitted radar signal and a measured phase of a receiving echo of said two coherent receiving channels;
and
wherein the arrangement is embodied as an interferometric ROSAR system, and positioned in such a way that each relevant area of the field to be measured can be detected, wherein for obtaining an image of the overall situation, ROSAR systems form a data network when linked together.
