Radar method and radar system for a phase-coherent analysis

Abstract

The invention describes a radar method for the coherent evaluation of radar signals in a radar system, in particular a multistatic radar system, wherein at least one or a plurality of received signals is/are received in several signal channels of an antenna arrangement, and wherein a synthetic received signal of a virtual transmitting and receiving antenna is generated using at least one composition model on the basis of the one or more received signals. The invention further describes a radar system according to claim 9 as well as a use of the radar system according to claim 14. The invention enables coherent evaluation of radar signals without the need to use a reciprocal signal propagation channel between the participating radar units of the radar system.

Dependencies are inferred from the claim text.
