• 英语翻译a.Fourier red noise spectrumMany geophysical time series can be modeled aseither white noise or red noise.A simple model for rednoise is the univariate lag-1 autoregressive [AR(1),orMarkov] process:（公式不用翻译）where a is the assumed lag-1 autocorrelation,x0 = 0,and zn is taken from Gaussian white noise.FollowingGilman et al.(1963),the discrete Fourier power spectrumof (15),after normalizing,is公式where k = 0 … N/2 is the frequency index.Thus,bychoosing
• 英语翻译Fig.12 shows the simulation results for 45º and -45º dual-polarized array antennas with VSWR and return loss of 1.299 and -17.72 dB respectively at the resonant frequency.Again,this proves that the combination of more patches in the array antenna can improve the VSWR and RL.Fig.13 shows the radiation pattern for 45º and -45º polarized dual-polarization array antenna.4.Measurement Results The same parameters involve in the simulation were measured

• 英语翻译Variations of the feedback gains with cable length for mt = 0 and the load mass for L =0using the reduced state feedback controller are shown in Fig.(4).We can notice that K isinversely proportional to the cable length because the load natural frequency increases withthe length which decreases the system settling time and consequently increases K
