An imaging method is provided for imaging or locating an object with a wave-based sensor. A wave field emanates from the object as an object signal, with this object signal emanating from a sensor is received at a sensor position, and wherein the sensor(s) and the object assume a number of spatial positions with respect to each other and form a synthetic aperture, and an echo signal is sensed at each of these sensor positions, a number of function values is extracted from the echo signals, which are allocated to a space coordinate of the object, and a signal with a residual phase characteristic is formed from the function values. Based on a residual phase characteristic that is due to a deviation of real sensor positions from assumed or measured sensor positions, an image point, the object position or the relative movement of the object is determined.
