  • Method for electromagnetically characterizing a target
    Patent number: 9372258
    Abstract: A method for electromechanically characterizing an object placed in a chamber, at least some walls of which have low absorbance at said frequency, one of the chamber walls being provided with an antenna array. In a first step, the parameters S of a first system consisting of the chamber and the antenna array are measured and in a second step, the same parameters S of a second system consisting of the chamber, the object and the antenna array are measured. The parameters S of the first system are subtracted from the parameters S of the second system to obtain a matrix of corrected parameters that is then diagonalized. The eigenvalues of the matrix constitute a characteristic electromagnetic signature of said object.
