sph2pol EMTTOOL swr

EMTTOOL >> EMTTOOL > steer

steer

steer array towards given angle

Calling Sequence

asteer = steer(d, a, ph0)

Parameters

a

array weights to be scanned (must be row vector)

d

element spacing in units of lambda

ph0

steering angle in degrees (broadside ph0=90)

asteer

steered weights (row vector)

Description

steer(d,a,ph0) can be used to steer array towards given angle. multiplies array weights by progressive phase, asteer(n) = a(n) * exp(-j*(n-(N-1)/2)*ps0), for n = 0,1,...,N-1, where ps0 = k*d*cos(ph0), thus, equivalent to scan(a, ps0)

Examples
