1. A method comprising:
determining, over a plurality of target ranges, antenna responses obtained with an electromagnetic sensor that is positioned in free space;
determining, for the plurality of target ranges, multi-path effects and near-field effects on the electromagnetic sensor when located on a vehicle;
based on the antenna responses with the multi-path effects and the near-field effects, generating a response map of expected responses for the electromagnetic sensor given a plurality of single-point locations proximate the vehicle, each expected response accounting for a corresponding angular and range dependent ground effect determined for that single-point location; and
outputting the response map to a sensor simulator configured to test detection accuracy of a simulated object located at a particular single-point location given the expected response defined by the response map for that particular single-point location.
