A fundamental Doppler-like but asymmetric wave effect that shifts receivedsignals in frequency in proportion to their respective source distances, wasrecently described as means for a whole new generation of communicationtechnology using angle and distance, potentially replacing TDM, FDM or CDMA,for multiplexing. It is equivalent to wave packet compression by scaling oftime at the receiver, converting path-dependent phase into distance-dependentshifts, and can multiply the capacity of physical channels. The effect washitherto unsuspected in physics, appears to be responsible for both thecosmological acceleration and the Pioneer 10/11 anomaly, and is exhibited inaudio data. This paper discusses how it may be exploited for instant, passiveranging of signal sources, for verification, rescue and navigation; incoherentaperture synthesis for smaller, yet more accurate radars; universal immunity tojamming or interference; and precision frequency scaling of radiant energy ingeneral.
