I read recent version of Yamaguchi decomposition (2013) that is applied on multi-look SAR imagery. I need to apply Yamaguchi on SLC product and should not apply any filtering (for this specific application) that will be converting to multi look. Multi-look product is also recommended in PCI Geometica although it works on SLC product too. While applying to SLC product, it always produces surface, double bounce and volume component. I wonder any one knows why this is happening. TIA.
I recommend you using PolSARpro to have a better control in selecting a function.

Dear Md Saimoom Ferdous ,
It's not possible to implement the target decomposition techniques on SLC SAR data and you need to estimate the polarimetric covariance or coherency matrix first. For doing so, a Boxcar filtering (with window size greater than 3) should be applied whereby, the speckle noise will be reduced and an unbiased estimate of the coherency/covariance matrix will be achieved.
Good luck!
