Abstract
The invention relates to a method and system for testing and evaluating a response of an automotive radar system for a specific automotive safety scenario, wherein the method and system generates a simulated reflected radar signature corresponding to at least one virtual target in a specific virtual scenario. The simulated radar signature is generated from one or more of: a pre-recorded real reflected radar signature from at least one real target in a specific real scenario, an analytical representation of a radar target signature from at least one virtual target in a specific virtual scenario.
