Target detection based on L- and C-band PolSAR data

For SAR signals with different frequency, the scattering characteristic of objects is generally different. Hence, more information can be obtained with multi-frequency SAR. It is easier to detect different targets by using multi-frequency PolSAR data, and even for the man-made targets in forest area. To effectively detect natural and man-made targets, the scattering components of different scattering mechanisms obtained from Land C-band PolSAR data by using polarimetric target decomposition could be combined. The experiment result indicates that different targets can be detected by using multi-frequency PolSAR data.
