find Dolph-Chebyshev array weights
[a, dph] = dolph(d, ph0, N, R)
element spacing in units of lambda
beam angle in degrees (broadside ph0=90)
number of array elements (even or odd)
relative sidelobe level in dB, (e.g. R = 30)
row vector of array weights (steered toward ph0)
3-dB beamwidth in degrees
dolph(d, ph0, N, R) computes the Dolph-Chebyshev array weights. array factor is Chebyshev A(psi) = T_{N-1}(x), x = x0 * cos(psi/2)
add sample pgm
This function uses the functions steer, poly2 and bwidth.
