A processor-implemented method is provided. An important characteristic of the invention is that the sole plate of the iron is lifted in a direction including a vertical vector, with a plane of the sole plate remaining roughly horizontal. The spreading tube defines therein at least one outlet hole for release of the thermal medium material contained in the injector. The second side has a chronological scale, preferably in months and years, inscribed thereon and also has at least one recording surface associated with the chronological scale. A set of complex weights is generated and applied to the radar return signal data to null scatterers associated with the class corresponding to ballistic acceleration.
