2L-IHP Algorithm for Target Detection and Its Applications in AIRSAR Data
2L-IHP目标检测算法及其在AIRSAR数据中的应用

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.
