Penelitian ini bertujuan untuk membuat transceiver SFCW-GPR yang mampu mendeteksi suatu target di dalam tanah atau pasir maupun di balik dinding yang terbuat dari beton. Sebelum realisasi, terlebih dahulu dilakukan simulasi pada level sistem menggunakan SystemVueTM dan MATLAB®. Simulasi dilakukan berdasarkan diagram blok dan spesifikasi yang telah ditentukan dengan memperhatikan ketersediaan komponen di pasar. Dari hasil simulasi diperoleh bahwa sistem SFCW-GPR ini memiliki resolusi 9,5 cm dan jarak tidak ambigu 6,08 m. Dalam simulasi juga ditunjukkan pengaruh frekuensi harmonisa pada hasil rekonstruksi sinyal dan jarak maksimum target yang masih dapat dideteksi dengan link budget yang tersedia. Berdasarkan pengujian yang dilakukan di laboratorium baik subsistem maupun sistem secara keseluruhan, transceiver memenuhi spesifikasi yang telah ditentukan. Sebelum dilakukan pengujian untuk men-sensing suatu target terlebih dahulu dilakukan uji kalibrasi dilakukan untuk menguji linieritas fasa. Berdasarkan hasil pengujian di laboratorium, sistem SFCW-GPR mampu mendeteksi keberadaan suatu target di balik tembok.

Deskripsi Alternatif :

The objective of this research is to develop a SFCW-GPR transceiver that can detect a target in the soil or sand as well as behind concrete wall. Prior to the realization, first of all is simulation in a level system using SystemVueTM and MATLAB®. The simulation is based on block diagram and specification which have been determined regarding to the availability of components on the market. The result that can be obtain from simulation is that SFCW-GPR has 9.5 cm of resolution and unambiguous range 6.08 m. The influence of harmonics frequency to the signal reconstruction result and the maximum distance of target which still can be detected with the availability of link budget will be demonstrated in the simulation. Based on measurement in the laboratory both subsystem and overall system, transceiver meets the specifications have been determined. Calibration should be done before the system will be used for sensing a target that is to check the linearity of phase. This SFCW-GPR system can detect the presence of a target behind a concrete wall based on the result of laboratory measurement.
