Abstract :
A random perturbation about the true position of a target image is shown to improve the position-detection accuracy of systems which operate on quantized data. For a two-sensor receptor the random perturbation is shown to decrease the position error measurably. For a multisensor receptor the random perturbation is shown to drive the position error to zero.
