NonSin_Beamforming3
说明: 非正弦信号的波束形成程序,和利用相位的常规波束形成不同,非正弦信号的波束形成首先匹配滤波,提取包络,然后延时相加,(Non-sinusoidal signal beamforming process, and the use of conventional beam-forming phase is different from non-sinusoidal signals in the first match beamforming filtering, envelope extraction, and then add delay,)

New-Text-Document-(2)
he form of the Burgers equation considered here is:
du du d^2 u
-- + u * -- = nu * -----
dt dx dx^2
for -1.0 < x < +1.0, and 0.0 < t.
Initial conditions are u(x,0) = - sin(pi*x). Boundary conditions are u(-1,t) = u(+1,t) = 0. The viscosity parameter nu is taken to be 0.01 / pi, although this is not essential.
The authors note an integral representation for the solution u(x,t), and present a better version of the formula that is amenable to approximation using Hermite quadrature.
This program library does little more than evaluate the exact solution at a user-specified set of points, using the quadrature rule. Internally, the order of this quadrature rule is set to 8, but the user can easily modify this value if greater accuracy is desired.
