Abstract
A way of using forward scattering to form images of a moving scatterer (MS) along its entire motion path is proposed and achieved in a full-scale experiment. Previously, this was done at the point where the MS signal was maximum, since the signal level during the MS’s movement decreased in accordance with its radiation directivity at a constant interference level. In the proposed MS signal detection method, a horizontal array is used in a different way, so that interference also decreases in accordance with the directivity of the horizontal array. This creates conditions for the formation of the signal of a passing MS, the form of which the interference can neither receive nor mask. The method was successfully applied in a full-scale experiment in 1998.
