Abstract :
CPM waveforms, having limited spectral spill, are considered viable as radar waveforms. Laurent Decomposition, which expresses the CPM waveform as the sum of PAM components, is investigated for CPM radar waveform design. Mismatched filter design results based on the Laurent decomposition and improved spectrum limitation associated with waveform generation based on PAM components are presented. Generating CPM waveform by utilizing PAM components inherently shapes pulse rising and falling edges and improves the spectrum roll-off significantly.
