Abstract:
A method for reconstructing an amplitude/phase diagram of a transmit/receive module for a phased-array antenna comprising:measuring an amplitude and a phase of amplitude/phase states (a, i), where i=imin . . . imax of an amplitude state a; measuring an amplitude and a phase of amplitude/phase states (j, b), where i=jmin . . . jmax of a phase state b; reconstructing amplitude values of an amplitude state x by shifting measured amplitude values of said amplitude state a by a difference &Dgr;A of measured amplitude values of amplitude/phase states (x, b) and (a, b), which within said phase state b belong simultaneously to either said amplitude state x or said amplitude state a; and reconstructing phase values of a phase state y by shifting measured phase values of said phase state b by a difference &Dgr;&PHgr; of measured phase values of amplitude/phase states (a, y) and (a, b), which within said amplitude state a belong simultaneously to either said phase state y or said phase state b.
