Abstract
Abstract The object of this invention is to provide a new nonuniformly spaced antenna array, where the most optimum positions of the array elements, and their corresponding amplitudes, are systematically determined by a rigorous synthesis technique of the given radiation pattern, and/or its requirements and specifications, in order to achieve it with the minimum possible number of array elements. This new array will be designated the Nonuniformly, Optimally Spaced Antenna Array, or in short, the NOSA Array.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
56 words
A method for optimizing the spacing and amplitude of the individual elements in a non-uniformly spaced array, as compared to a conventional uniformly spaced array, in order to accomplish a given radiation pattern, and/or its requirements and specifications, with the minimum number of elements, said method based on the following relationship for a symmetric linear array:
Claim 2
Independent Claim
56 words
A method for optimizing the spacing and amplitude of the individual elements in a non-uniformly spaced array, as compared to a conventional uniformly spaced array, in order to accomplish a given radiation pattern, and/or its requirements and specifications, with the minimum number of elements, said method based on the following relationship for a symmetric linear array:
Claim 3
Dependent Claim
61 words
A method for optimizing the spacing and the amplitude of the individual elements in a non-uniformly spaced non-symmetric array, as compared to a conventional uniformly spaced array, in order to accomplish a given radiation pattern with the minimum number of elements, said method accomplished essentially as in claim 1, except it is based on the following relationship for a non-symmetric array:
Claim 4
Dependent Claim
43 words
An arrangement of a set of elements in a non-uniformly optimally spaced array, as specified in claim 1, in which each element is an electromagnetic antenna radiator or receiver, like dipole, slot, horn, aperture, dish, parabolic reflector, etc. or a combination of them.
Claim 5
Dependent Claim
41 words
An arrangement of a set of elements in a non-uniformly optimally spaced array, as specified in claim 1, in which each element is an acoustic or sonar radiator or receiver, or a combination of them, used under water or above water.
Claim 6
Dependent Claim
44 words
An arrangement of a set of elements in a non-uniformly optimally spaced array, as specified in claim 1, in which each element is a seismic radiator or receiver, like geophone, seismometer, seismograph, etc. or a combination of them, used under ground or above ground.
Claim 7
Dependent Claim
19 words
An array comprising a grouping of subarrays each designed in accordance with the method set out in claim 1.
