Title: Sonar beam-forming
IPC: G10K11/34
Filed: 1979-06-14
Abstract: The outputs from the sonar detectors of a circular array 76 are fed to two weighting networks 77 and 78 whose respective outputs are summed at 79, 80 to produce two mutually orthogonal transforms. The transforms are then brought into phase quadrature by respective modulation by a sine and cosine function. The phase quadratured transforms are then added by the summer 91. In order to provide a scanning beam it is the values of the weighting factors in the networks 77 and 78 which are varied. This is done by weighting each detector output by a respective programmable multiplying D/A converter. A digitised version of the correct wave function is stored in a ROM connected to each of the D/A converters. <IMAGE>
