1. An imaging method with a synthetic aperture for determining at least one of an incident angle and a distance of a sensor from at least one object in space, comprising:

  • sensing, at a number of aperture points, one respective echo profile;

    calculating at least one of one phase correction value and one distance correction value for each of a plurality of assumed angles as the at least one incident angle;

    generating adapted profiles based the echo profiles by at least one of adapting the phase by the phase correction value for each of the assumed angles and shifting the distance by the distance correction value;

    forming a probability distribution for the assumed angles from the adapted profiles; and

    determining at least one of a probability value for the incident angle and the distance from the probability distribution.
