Abstract :
This paper investigates different metrics for indication of ground moving targets in multi-channel SAR data (SAR-GMTI). These metrics have in common that they are all based on the eigen-decomposition of the sample covariance matrix. Their statistical properties are analytically compared and their detection capabilities, demonstrated on measured two-channel airborne data.
