Claim 0:
1. A method of emulating echo signals reflections from an emulated target during radar testing, the method comprising:
identifying a first end point and a second end point of the emulated target;
acquiring a radar signal from a radar sensor, the radar sensor including a one or more transmit elements for sending the radar signals and a plurality of receive elements;
generating emulated echo signals, responsive to the acquired radar signal, corresponding to a plurality of target points on the emulated target, the plurality of target points including the first end point, the second end point, and reference points located on a line connecting the first end point and the second end point, by repeatedly identifying descriptive attributes respectively corresponding to each of the target points during an integration period of the radar sensor, wherein the descriptive attributes corresponding to each of the reference points are identified by interpolating between the corresponding descriptive attributes of the first and second end points; and
applying the emulated echo signals to the receive elements of the radar sensor, respectively, during the integration period, wherein the emulated echo signals represent the emulated target from the first end point to the second end point, and wherein the radar sensor calculates a relative position of the emulated target using the descriptive attributes of the target points corresponding to the emulated echo signals.
