Abstract
Active module integrated into an electronically scanned antenna, and radar comprising such an antenna, applied especially to meteorology. The present invention relates to an active module integrated into an electronically scanned antenna. The active module, suitable for radiofrequency transmission, includes at least one power amplifier. This power amplifier delivers a signal that feeds one or more radiating elements. The active module includes at least one waveform generator that delivers a phase-controllable signal to the power amplifier. Another subject of the invention is an electronically scanned antenna comprising radiating elements, each radiating element being fed via at least one active module according to the invention. Yet another subject of the invention is a radar comprising at least one antenna according to the invention. The invention applies to radars and to communication systems employing radiofrequency transmit and receive functions with electronic scanning, such as for example weather radars.
