According to CTBT treaty, Ground Penetrating Radar (GPR), together with magnetic and gravitational field mapping and electrical conductivity measurements, are non-destructive geophysical detection technology which can achieve effective detection of OSI anomalies or artifacts underground. As a matter of fact, GPRs have been commercially widely used for decades to conduct safety inspection of underground gas pipelines of cities and towns. It has also been commercially widely used to detect caves under the paved roads to avoid any unexpected land subsidence accident. This work is the active result of joint efforts made by experts of OSI and experts of commercial GPR application. Based on the rich experience and data accumulation of underground pipelines and caves detection, customized radar detector design and data processing mechanism suitable for CTBT OSI scenarios has been put forward. According to the requirements of different geological environment, working frequency of radar ranging from 50MHz to 1GHz can be customarily designed, so as to make the GPRs meet with practical requirements of real OSI scenarios. Moreover, the GPRs would be made user-friendly based on Android operating system, with touch screens and blue tooth data communication capability, etc.
This work would bring GPRs’ commercial application together with CTBT OSI practical requirements, which could provide another optional choice for OSI essential equipment development.
