Multicarrier Coherent Pulse Shaping for Radar and Corresponding Signal Processing

A new pulse shaping approach based on coherent superposition of multiple carriers in radar is introduced, by which a shorter efficient pulse width waveform can be formed. At the receiver end, breaking the echo into multiple corresponding frequency components, multiple series can be taken from those individual components, then recombining these components to achieve the signal processing gain. Three processing approaches are proposed for multicarrier Doppler processing, which will provide better Doppler estimate performances than that of conventional pulse Doppler radar.
