Dual-channel SAR slow moving target detection method based on multi-look and magnitude-phase joint

Aiming at the problem of the detecting difficulty and imaging the slow moving target submerged in clutter and noise, a dual-channel SAR slow moving target detection method based on multi-look and magnitude-phase joint is proposed. Firstly, according to statistical analysis of interferogram's phase and magnitude PDF distribution, a new metrics is established by combining the variable of interferogram's phase transformation with interferogram's magnitude. Then, the new metrics is processed by multi-look. Finally, slow moving target can be effectively detected by a given CFAR threshold. Experiments show the effectiveness of the algorithm.
