Abstract
A method for remotely neutralizing a target. The method includes transmission by a probe antenna toward the target of a test signal having a frequency spectrum having at least two distinct test frequencies; reception by an array of at least two antennas of a plurality of waves scattered by the target in response to the test signal. For each antenna of the array the method includes measuring a representative value of the amplitude of the waves scattered by the target as a function of the test frequencies; choosing at least one favored transmission frequency as a function of the representative value of the amplitude of the scattered waves; and transmitting at least one radiofrequency wave toward the target at a minimum of one favored frequency chosen for that antenna with a phase ensuring the coherent addition on the target of the radiofrequency waves transmitted by the antennas of the array.

11. A method for neutralizing a target, comprising the following steps:
-
the transmission by a probe antenna toward the target of a test signal comprising at least one test radiofrequency wave and having a frequency spectrum comprising at least two distinct test frequencies; reception by an array of at least two antennas (Ei) of a plurality of waves scattered by the target in response to the test signal, each antenna of the array receiving at least one wave scattered by the target; said method being characterized in that it comprises at least the following steps; measuring a representative value of the amplitude of the waves scattered by the target as a function of the transmission test frequencies of the radiofrequency waves; choosing, for each antenna (Ei) of the array, at least one favored transmission frequency as a function of the representative value of the amplitude of the scattered waves; and transmitting, by each antenna (Ei) of the array, at least one radiofrequency wave toward the target at a minimum of one favored frequency chosen beforehand for that antenna with a phase ensuring the coherent addition on the target of the radiofrequency waves transmitted by the antennas of the array. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
