Phasor Quaternion Neural Network Framework and Its Significance in Big SAR Intelligence

Abstract

In this paper, first we overview the use of artificial intelligence (AI) in observation and data processing in synthetic aperture radar (SAR). Then we discuss the function and significance of phasor-quaternion neural networks (PQNN) in this field. In particular, we describe its effectiveness in dealing with polarimetric-interferometric synthetic aperture radar (PolInSAR) observation and its data utilization.
