Abstract
The disclosure relates to the recognition of an objective known as an IFF or 'Identification Friend or Foe' system. In the interrogator unit of the IFF system, the signals received undergo processing operations that take account of the characteristics of the antenna and enable the useful information to be separated from the disturbances. In order to be able to use an electronic scanning antenna in spite of the fact that it has characteristics which vary with the training angle, hence with the direction in which the objective is located, the processing operations to be performed are designed for different training angles, the characteristics of these processing operations are memorized and the processing operations are performed as a function of the training angle.
