Modeling-Rayleigh-fading-channel-based-on-modifie
This Matlab Code models a Rayleigh fading channel using a modified Jakes channel model.
A modified Jakes model chooses slightly different spacings for the scatterers and scales their waveforms using Walsh–Hadamard sequences to ensure zero cross-correlation.
alpha_n = frac{pi(n-0.5)}{2M} and eta_n = frac{pi n}{M},
results in the following model, usually termed the Dent model or the modified Jakes model:
R(t,k) = sqrt{frac{2}{M}} sum_{n=1}^{M} A_k(n)left( cos{eta_n} + jsin{eta_n}
ight)cos{left(2pi f_d t cos{alpha_n} + heta_{n}
ight)}.
The weighting functions A_k(n) are the kth Walsh–Hadamard sequence in n. Since these have zero cross-correlation by design, this model results in uncorrelated waveforms. The phases ,! heta_{n} are initialized randomly and have no effect on the correlation properties. Matlab fast Walsh-Hadamard transform function is used to efficiently generate samples using this model.

逆合成孔径雷达（ISAR）具有远距离、全天候、全天时工作等优点，目前通过ISAR成像来进行目标识别已得到广泛的应用。ISAR的观测对象是非合作目标，因此ISAR成像具有深远的国防应用背景，受到各国的重视，是竞争激烈、发展迅速的技术领域。(Inverse Synthetic Aperture Radar (ISAR) has a long-range, all-weather, all-time work, etc, currently conducted by ISAR imaging for target identification has been widely used. ISAR target non-cooperative target observation, it has far-reaching defense ISAR imaging application background, attention all, is highly competitive, rapidly developing technology.)
