2L-IHP algorithm for man-made target detection is discussed briefly first.In order to apply it widely

it is modified to circumvent the constraint of the data.For polarimetric SAR images

PWF is used to generate an image for target detection.According to ADTS dataset

these algorithms are analyzed and evaluated respectively.C-、L- and P-band AIRSAR data are also processed

and we derive some conclusions.Considering the penetrating ability of the microwave

C- and L-band SAR data obtain the best detecting accuracy among the three bands.HH polarization performs better than VV and HV polarization for man-made target detection.Moreover

because more information is contained in polarimetric SAR data

they should get better detecting results theoretically.It is concluded from the experiments that polarimetric SAR data have advantages over single channel SAR data when they are applied for man-made target detection

which is consistent to the theoretical analysis.But all these conclusions need further validation.
