Spectral-shape optimized FM noise radar for pulse agility

A non-repeating, spectrum-optimized FM waveform suitable for radar pulse agility is described. The waveform is an alternative manifestation of the recently developed pseudo-random optimized (PRO) FMCW framework for FM noise radar, now implemented in a pulsed form. Each pulsed FM waveform is iteratively optimized to match a spectrum shape with low range sidelobes and good spectral properties, while the random initialization for each waveform ensures sufficient diversity that the resulting optimized form is unique, thereby providing decoherence of range sidelobes. The performance of this pulse-agile structure is examined in simulation and subsequently demonstrated with measured results of static and moving targets.
