Title
(EN) Chirp travelling wave solutions and spectra
(ZH) 线性调频行波解及谱
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.
(ZH) 本发明涉及波的谱分量,谱分量具有一个或多个不同于相位和幅度的在接收器处随时间单调地变换的特性,并且提供与从波源至接收器的传播的时间或距离成比例的变化延迟或滞后。滞后涉及在离开源之处的特性值,并且不存在于源的附近。延迟的与调制信息的正交性使得它们可用于测距以及用于通过它们的源距离进行信号分离或隔离。频率和波长的滞后允许物理信道的容量倍增。滞后波长的沿着从源到接收器的整个路径的恒定性使得能够通过在源波长处不可用的信道或介质进行接收,并且在不同于照明的波长处进行成像。
