Cross_spectra The Cross Spectum.In normal spectral analysis the spectrum shows how energy is distributed in frequency (or wavenumber) space. This can be obtained either by taking the fourier transform of the lagged autocorrelation. The lagged autocorrelation is infact the convolution of a time ...
仍将执行每个指定序列的单变量分析。 您可以指定CROSS NO以在使用APPLY应用先前模型时关闭双变量分析。 示例 SPECTRA VARIABLES = VARX VARY VARZ /CROSS. 在此示例中,除了VARX,VARY和VARZ的通常单变量分析外,还请求使用具有VARY的序列VARX和具有VARZ的VARX的双变量谱分析。

本文提出一种新的同步被动式测距法,这种方法具有波束行程短、传播衰减小和抗假目标能力强等优点,以超声波作为测距波束即可满足测量车距的要求。4) Passive Cross-correlating Direction 互相关法被动测向5) passive distance and velocity measuring 被动测距和测速 1. Besides,the passive distance and velocity measu...
The cross-correlation functions (CCFs) and cross spectra expected for quasi-periodic oscillation (QPO) shot noise models are calculated under various assumptions, and the results are compared to observations. Effects due to possible coherence of the QPO oscillations are included. General formulas for...
In preparation for the next SAR-X/SIR-C Shuttle mission, we devised an experiment aimed to compare the classical HH inversion algorithm for the retrieval of ocean wave spectra from SAR images, with a new method based on the use of cross-spectra. The results obtained with the two methods ar...
