Method And Apparatus For Determining And Forming Delayed Waveforms For Forming Transmitting Or Receiving Beams For A Sonar System Array Of Transmitting Or Receiving Elements

Assignee:
Sonetech Corporation - Bedford NH
International Classification:
G06F 1518
US Classification:
706 13, 342373, 367103, 367137
Abstract:
Sonar method and system for determining and using beamform factors for forming sonar beams approximating an optimum sonar beam for the directional transmission or reception of sonar energy by a sonar phased array system. Optimum maximum and minimum dependent beamform factors are determined from initial beamform factors and an initial parent population of chromosomes is generated, each chromosome including a gene corresponding to a dependent beamform factor and representing an initial candidate beam. Subsequent parent populations are generated by chromosome cloning. A child population is generated from a parent population by exchanging statistically selected pairs of genes and generating a mutated population. A surviving population is selected from the mutated population by a chromosomes comparison. When the surviving population chromosomes meet the criteria, the best match genes of the surviving population are selected for forming a beam.

US Classification:
706 13, 342373
Abstract:
An acoustic imaging system for forming acoustic beams approximating an optimum acoustic beam for the directional transmission or reception of acoustic energy. Maximum and minimum dependent beamform factors are determined from initial beamform factors and an initial parent population of chromosomes is generated, each chromosome including a gene corresponding to a dependent beamform factor and representing an initial candidate beam and subsequent parent populations are generated by cloning of the surviving populations. A child population is generated by exchanging statistically selected pairs of genes of the parent population and generating a mutated population. A surviving population is selected from the mutated population of the mutated population with a fitness criteria. When a chromosome of the surviving population meets the solution criteria, the genes of the surviving population having the best match to the fitness criteria are selected to forming a beam.

International Classification:
G06F 1518 H01Q 326 G01S 380
US Classification:
706 13
Abstract:
A method and system for use in an air acoustic system for determining and using beamform factors for forming air acoustic beams approximating an optimum air acoustic beam for the directional transmission or reception of air acoustic energy by an air acoustic phased array system. Maximum and minimum dependent beamform factors of an optimum beam are determined from initial beamform factors and an initial parent population of chromosomes is generated, each chromosome including a gene corresponding to a dependent beamform factor and representing an initial candidate beam and subsequent parent populations are generated by cloning of the chromosomes of surviving populations. A child population is generated from a parent population by exchanging statistically selected pairs of genes of the parent population and generating a mutated population from the child population by mutating statistically selected genes of the child population. A surviving population is selected from the mutated population by comparing the chromosomes of the mutated population with a fitness criteria and selecting the chromosomes of the mutated population meeting the fitness criteria. When a chromosome of the surviving population meets the solution criteria, the genes of the surviving population having the best match to the fitness criteria are selected to forming a beam.

Abstract:
A method and system for use in an radio frequency system for determining and using beamform factors for forming radio frequency beams approximating an optimum radio frequency beam for the directional transmission or reception of radio frequency energy by an radio frequency phased array system.
