ABSTRACT:
Disclosed is an anti-icer system that can be used to neutralize the effects of a nuclear electromagnetic pulse or of parasitic electromagnetic fields coming from other radars transmitting in the vicinity. This anti-icer comprises a sheet of conductive wires positioned on a screen placed before the aperture of the radar antenna and connected in series/parallel combinations to the terminals of a supply source so that each is crossed by a heating current. The conductive wires of the sheet and their interconnections form at least one pair of patterns, on the screen, that are symmetrical with reference to an axis. This symmetry provides for a neutralization by opposition of the induced electromotive forces. FIG. 2.
