Abstract
Abstract A partially adaptive array which compensates for jamming. The array is comprised of more than 1000 elements and uses a bootlace lens to form a family of beams from which an adaptive array chooses at least one beam of the family of beams that most closely represents the jamming, and subtracts the beam from a main beam. In this way jamming of the beam is compensated for.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
A partially adaptive array of antenna which compensates for jamming comprising: more than 1000 elements of antenna, said elements receiving radio frequency energy and producing a linear output proportional thereto, said elements together forming a plane; means for forming a main beam from the output of said elements; a bootlace lens having a plurality of predetermined input positions with each of said elements connected to said bootlace lens at a predetermined position so the output from each element is supplied to said bootlace lens to form a family of beams; an adaptive processor connected to said bootlace lens to receive said family of beams for determining whether one or more beams from said family of beams contains jamming radiation; subtractor means connected to the main beam and the adaptive processor and receiving said jamming radiation containing beams and subtracting them from said main beam to remove the effects of jamming.
Claim 2
Dependent Claim
150 words
A partially adaptive array of antenna which compensates for jamming comprising: more than 1000 elements of antenna, said elements receiving radio frequency energy and producing a linear output proportional thereto, said elements together forming a plane; means for forming a main beam from the output of said elements; a bootlace lens having a plurality of predetermined input positions with each of said elements connected to said bootlace lens at a predetermined position so the output from each element is supplied to said bootlace lens to form a family of beams; an adaptive processor connected to said bootlace lens to receive said family of beams for determining whether one or more beams from said family of beams contains jamming radiation; subtractor means connected to the main beam and the adaptive processor and receiving said jamming radiation containing beams and subtracting them from said main beam to remove the effects of jamming.
Claim 3
Dependent Claim
15 words
A partially adaptive array as described in claim 1 wherein said elements are T.V. antennae.
Claim 4
Dependent Claim
24 words
A partially adaptive array as described in claim 1 wherein said means for forming a main beam is a beam form and feed network.
Claim 5
Dependent Claim
156 words
A partially adaptive array of antennae which compensates for jamming comprising: more than 1000 T.V. antennae, said antennae receiving radio frequency energy and producing a linear output proportional thereto, said antennae together forming a plane; a beam form and feed network for forming a main beam from the output of said antennae; a bootlace lens having a plurality of predetermined input positions with each of said antennae connected to said bootlace lens at a predetermined position so the output from each antenna is supplied to said bootlace lens to form a family of beams; an adaptive processor connected to said bootlace lens to receive said family of beams for determining whether one or more beams from said family of beams contains jamming radiation; and a subtractor means connected to the main beam and the adaptive processor and receiving said jamming radiation containing beams and subtracting them from said main beams to remove the effects of jamming.
Claim 6
Dependent Claim
156 words
A partially adaptive array of antennae which compensates for jamming comprising: more than 1000 T.V. antennae, said antennae receiving radio frequency energy and producing a linear output proportional thereto, said antennae together forming a plane; a beam form and feed network for forming a main beam from the output of said antennae; a bootlace lens having a plurality of predetermined input positions with each of said antennae connected to said bootlace lens at a predetermined position so the output from each antenna is supplied to said bootlace lens to form a family of beams; an adaptive processor connected to said bootlace lens to receive said family of beams for determining whether one or more beams from said family of beams contains jamming radiation; and a subtractor means connected to the main beam and the adaptive processor and receiving said jamming radiation containing beams and subtracting them from said main beams to remove the effects of jamming.
