Summary: This letter proposes a method for handheld ground penetrating radar (GPR) sensor in landmine detection to compensate for the irregularities in ground reflection arrival time. By selecting the frequency with the highest power of the ground surface reflection and equalizing the phase of the received signal at that frequency, the irregular reflection can be compensated, resulting in a uniform ground reflection signal and improved quality of the target shape.

Summary: This study presents an improved handheld FFOCT system based on the tandem structure of Michelson interferometer and Fizeau interferometer. The impact of wave aberrations and refractive index difference on the system point spread function (PSF) is analyzed, and the limitations of orientation deviation and measuring depth are studied. Experimental results validate the theoretical analyses, showing that reducing the refractive index difference can increase the imaging depth of the handheld FFOCT system.
