Background principle of detecting a moving object

According to the traditional views, the problem that arises upon detecting a moving object lies in the fact that the object reflects the sensing radiation to a lesser degree than the background which blacks out the useful signal. This problem also arises if there is no contrast between the object and background. Besides this passive noise, target detection is especially hindered by the deliberate active impact noise which "blinds" the locator. The present publication proposes a basically new approach to detecting moving objects. According to the new ideas, information about the object is obtained from what was traditionally regarded as noise (the coherent component of radiation reflected from a stationary background), whereas what was traditionally regarded as useful signal (radiation reflected from the target) is not taken into account, that is, is set to zero when processing the recorded radiation. A special case of this approach-generation of the holographic image of a moving object-is discussed by A. N. Anuashvili in a separate paper.
