Claim Text:
1. A beam former for monopulse beam forming in a phased array antenna comprising a first sub-array comprising a first plurality of antenna elements and a second sub-array comprising a second plurality of antenna elements, the beam former comprising: a sum beam former connected to the first plurality of antenna elements and the second plurality of antenna elements, and comprising an array sum output, a first delta sub-array beam former comprising: the first delta sub-array beam former being configured to provide a first plurality of delta over sum (D/S) weights with respect to the sum beam former, the first plurality of D/S weights varying substantially linearly, with a first gain increment, across the first sub-array; a second delta sub-array beam former comprising: the second delta sub-array beam former being configured to provide a second plurality of D/S weights with respect to the sum beam former, the second plurality of D/S weights varying substantially linearly, with a second gain increment, across the second sub-array; the first and second inline gain-phase modules being configured to provide a first gain increment and a second gain increment differing by at least 2 decibels (dB).
