scan

scan array with given scanning phase

Calling Sequence

ascan = scan(a, ps0)

Parameters

a

array weights to be scanned (must be row vector)

ps0

scanning phase in radians

ascan

scanned weights (row vector)

Description

scan(a, ps0) can be used to scan array with given scanning phase. multiplies array weights by progressive phase, ascan(n) = a(n) * exp(-j*(n-(N-1)/2)*ps0), n = 0,1,...,N-1. ps0 can be any phase, even outside visible region. steer is a special case of SCAN, that is, steer(d, a, ph0) = scan(a, 2*pi*d*cos(ph0))

Examples
