Kajian ini mencadangkan anggaran kebolehtelapan kerumitan rendah untuk aplikasi radar penembusan tanah berdasarkan pendekatan penyongsangan sumber kontras (CSI), dengan mengandaikan media tanah berbilang lapisan. Andaian kehomogenan untuk setiap lapisan latar belakang digunakan untuk menangani keadaan yang tidak jelas sambil mengekalkan ketepatan untuk pembinaan semula kebolehgunaan, dengan ketara mengurangkan bilangan yang tidak diketahui. Menggunakan tekaan awal yang sesuai untuk setiap lapisan, pendekatan pasca-CSI juga menyediakan profil dielektrik objek yang tertimbus. Ujian berangka domain masa perbezaan terhingga menunjukkan pendekatan yang dicadangkan dengan ketara meningkatkan ketepatan pembinaan semula untuk objek yang tertimbus berbanding dengan pendekatan CSI tradisional.

Abstract: This study proposes a low-complexity permittivity estimation for ground penetrating radar applications based on a contrast source inversion (CSI) approach, assuming multilayered ground media. The homogeneity assumption for each background layer is used to address the ill-posed condition while maintaining accuracy for permittivity reconstruction, significantly reducing the number of unknowns. Using an appropriate initial guess for each layer, the post-CSI approach also provides the dielectric profile of a buried object. The finite difference time domain numerical tests show that the proposed approach significantly enhances reconstruction accuracy for buried objects compared with the traditional CSI approach.
