Abstract :
The radiated spectrum of an active array in which each radiating element is driven by a separate transmit amplifier differs fundamentally from that of a passive array driven by a single large transmitter because of element-to-element variations in the finer details of the transmitted waveform. This paper analyzes the relation between the transmit amplifier and the overall array spectral perforrnance.
