Matlab Program For Dolph Chebyshev Arrayan
Matlab Program For Dolph Chebyshev Arrayan 3
Dolph–Chebyshev (DCA) Chebyshev≡Tschebyscheff Dolph proposed (in 1946) a method to design arrays with any desired side-lobe levels and any HPBWs. This method is based on the approximation of the pattern of the array by a Chebyshev polynomial of order m, high enough to meet the requirement for. Select a Web Site.

. If Wp is a scalar, then cheby1 designs a lowpass or highpass filter with edge frequency Wp. If Wp is the two-element vector w1 w2, where w1. It finds the lowpass analog prototype poles, zeros, and gain using the function. It converts the poles, zeros, and gain into state-space form. If required, it uses a state-space transformation to convert the lowpass filter to a highpass, bandpass, or bandstop filter with the desired frequency constraints. For digital filter design, it uses to convert the analog filter into a digital filter through a bilinear transformation with frequency prewarping.
Careful frequency adjustment enables the analog filters and the digital filters to have the same frequency response magnitude at Wp or w1 and w2. It converts the state-space filter back to transfer function or zero-pole-gain form, as required.
