A method for eliminating signals from false targets in MUSIC based GPR range profile

摘要

High range resolution (HRR) has many advantages in ground penetrating radar (GPR) [1]. Apart from providing the ability to resolve closely spaced targets in range, it improves range accuracy, reduces the amount of clutter within resolution cell, reduces multipath, provides high resolution profiles and aids in target classification. HRR provides characteristic features of objects, for example parameters connected with physical dimensions or shape. In the paper one of superresolution methods of obtaining unambiguous synthetic range profiling in SFCW radar was described. A method for eliminating signals from possible false targets generated by overestimation of number of actual targets in MUSIC algorithm was discussed.
