Abstract

Device for determining the direction of a plane wave comprising P detectors regularly spaced out on a rectilinear base, a clock whose frequency is 1/.tau. and several channels, each connected with a determined direction. The channel m comprises a device sampling all the m.tau. signals of the detectors whose outputs are connected to an adder followed by m - 1 delay cells in series, the output of the last one being applied to the input of the adder. Each adder supplies a signal depending on the difference between the direction m and the direction of the plane wave. Application is to sonars.
