Abstract

An emulation test system and method are provided for time adjusting emulated echo signals in response to a periodic electromagnetic signal. The method includes generating a scene simulation including a simulated object; generating a simulation frame indicating object transform information regarding the simulated object; calculating positions and velocities of an emulated targets corresponding to the simulated object using the object transform information; generating a ray tracing frame corresponding to the simulation frame indicating the calculated positions and velocities of the emulated targets; predicting a time point in a next feature in a feature pattern of the electromagnetic signal; calculating predicted target information of the simulated object at the predicted time point using the calculated positions and velocities; and generating an echo signal in response to the next burst of the electromagnetic signal using the predicted target information to compensate for latencies introduced by differences between real world and simulation times.
