Abstract
The method for locating a mobile unit relatively to an intermittent lighted beacon consists in calculating, on the basis of data concerning the mobile movement, the position of the discrete scatterer on the linear barrette obtained by a point by point subtraction of two linear images of the same image field, one wherein the beacon is alight and one wherein it is not alight, and the derivative of the position. On the basis of said data, the distance separating the beacon thus represented and a mark related to the mobile unit is calculated, and the beacon angular position relative to said mark linked with the mobile.
