Abstract
A method and device are provided for focusing the antennae of an array on a point to be examined. Each microwave signal received by an array antenna is subjected to amplitude modulation by means of a phase shifted low frequency modulation signal. The modulated signals are summed and the result of the summation is subjected to microwave detection then to low frequency demodulation by means of the modulation signal. The focusing point depends on the phase law by which the modulation signal is phase shifted so as to obtain each phase shifted modulation signal.
