Claim 6:
7. A target emulation system for testing a radar sensor having a plurality of radar transmit elements for providing a plurality of radar signals, and a plurality of radar receive elements for receiving a plurality of target echo signals responsive to the plurality of radar signals emulating reflections from an emulated target, defined at least in part by a first end point and a second end point, the system comprising:
one or more emulator receive elements for acquiring a radar signal from the radar sensor;
a processing unit, including a processor and a memory for storing computer readable code that, when executed by the processor, causes the processor to:
identify the first end point and the second end point of the emulated target; and
generate emulated echo signals, responsive to the radar signals, 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

a plurality of emulator transmit elements for 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.
