  One objective of this paper is to propose a novel class of sequence pairs,
called "Quasi-orthogonal Z-complementary pairs (QOZCPs)", each depicting
Z-complementary property for their aperiodic auto-correlation sums and also
have a zero correlation zone when their aperiodic cross-correlation is
considered. Construction of QOZCPs based on Successively Distributed Algorithms
under Majorization Minimization (SDAMM) is presented.
  Another objective of this paper is to apply the proposed QOZCPs in fully
polarimetric radar systems and analyse the corresponding ambiguity functions.
It turns out that QOZCP waveforms are much more Doppler resilient than the
known Golay complementary waveforms.
