Abstract:
A transmitter apparatus generates a RF pulse signal having alternating high-amplitude pulse-on intervals and low-amplitude pulse-off intervals, and supplies the RF pulse signal as respective individual transmission signals of antenna elements of an array antenna, with the individual transmission signals having a phase distribution during each pulse-on interval whereby a beam is transmitted from the antenna in a predetermined transmission direction. During each pulse-off interval, a different phase distribution is established for the individual transmission signals, thereby reducing the level of noise radiated in the transmission direction during each pulse-off interval.
