Title
(EN) CHIRP TRAVELLING WAVE SOLUTIONS AND SPECTRA
(FR) SOLUTIONS ET SPECTRES A ONDES PROGRESSIVES A FLUCTUATION DE LONGUEUR D'ONDE
Abstract
(EN) Spectral components of waves having one or more properties other than phase and amplitude that vary monotonically with time at a receiver, and provide retardations or lags in the variation in proportion to the times or distances travelled from the sources of the waves to the receiver. The lags denote the property values prior to departure from a source and are absent in its proximity. Orthogonality of the lags to modulated information makes them useful for ranging and for separation or isolation of signals by their source distances. Lags in frequencies and wavelengths permit multiplication of capacities of physical channels. Constancy of the lagging wavelengths along the entire path from a source to the receiver enables reception through channels or media unusable at the source wavelengths, as well as imaging at wavelengths different from the illumination.
(FR) La présente invention concerne des composantes spectrales d'ondes ayant une ou plusieurs propriétés autres que la phase et l'amplitude qui varient de façon monotone avec le temps au niveau d'un récepteur, et produisent des retards ou des décalages de la variation en proportion avec les temps ou distances parcourues des sources des ondes au récepteur. Les décalages indiquent les valeurs de propriété avant le départ depuis une source et sont absents à sa proximité. L'orthogonalité des décalages par rapport à des informations modulées les rend utiles pour la télémétrie et pour la séparation ou l'isolement de signaux par leurs distances par rapport à une source. Les décalages de fréquences et de longueurs d'onde permettent la multiplication de capacités de canaux physiques. La constance des longueurs d'onde de décalages le long du trajet total d'une source au récepteur permet la réception par l'intermédiaire de canaux ou de supports inutilisables aux longueurs d'onde de source, ainsi que l'imagerie à des longueurs d'onde différentes de l'éclairage.
