Super-resolution 2D-ISAR imaging techniques such as LP(linear prediction) and ESPRIT(Estimation of Signal Parameters via Rotational Invariance Techniques) are extended to full polarization 2D processing techniques using 2D full polarised scattering coefficients data for a target.
Finally, we realize a direction finding algorithm analysis platform based on the principle of software engineering. Using this platform we analyze and compare the performance of MUSIC direction finding algorithm and two other ESPRIT(Estimation of Signal Parameters via Rotational Invariance Techniques) algorithms. The results we attained are consistent with the theory research.

The rotation invariance and good recognition efficiency is achieved by using SDF(Synthetic Discrimination Functions) as the reference in the amplitude-modulated and a power spectrum subtracted joint transform correlator.
The introduction of dissipation and rotational invariance affects the acoustic birefringence, while the latter gives rise to an additional term in the expression for the phase shift.
The method is based on the rotational invariance techniques and uses an array triplet in motion to estimate the central frequencies and azimuths of coherent signals from narrowband sources.
An effective method is introduced to compensate the effects of mutual coupling for the Estimation of Signal Parameter via Rotational Invariance Techniques (ESPRIT) direction finding algorithm in application of signal snapshot array processing.
The regularized Least-Squares Estimation method of Signal Parameters via Rotational Invariance Techniques (LS-ESPRIT) is herein proposed for Direction-Of-Arrival (DOA) estimation of non-Gaussian sources with only one acoustic vector-sensor.

Computer simulation has shown that the light efficiency and the discrimination capability are greatly enhanced, and the full rotation invariance is preserved after the phase-shifting technique has been used.
For the rotation invariance and translation invariance of the centripetal code and the normalization of convex, the proposed retrieval method is similarity transform resistant, Experimental results confirm this capability.
Rotation invariance is achieved using the translation property of the polar-mapped circular patches.
The very quantization can be interpreted as a dynamical breakdown of a local spin rotation invariance and leads to spin-spin four-fennion interaction in a dynamical Higgs mechanism.
