Abstract
In conventional phased array antennas, multiple signals that perform different functions, such as radar, electronic warfare (EW) and telecommunications, can each be simultaneously transmitted only through a different sub-aperture of the array. For maximum power and efficiency in conventional phased array antennas, the power amplifiers operate on one signal at a time. The present invention forms a common waveform from multiple signals for transmission through a common aperture of a phased array antenna. In wideband operations, waveform-shaping and amplitude-to-phase-modulation are used to transmit high-power diverse waveforms through every element of the array.
