HZ-GPR Ground Penetrating Radar Series

Project backgd:

HZ-GPR serounries are the latest and highest-performance products of Hangzheng Co. Ltd. Jointly developed with a famous university in China, under the key project’s support of national high tech plan ‘863’. Its performance including hardware, data processing and system integration is advanced preparing with other similar products in China, and approaching to the same level of the most advanced GPR products all over the world. HZ-GPR can be widely used in the various of applications such as the detection and location of the subsurface pipelines, the detection of pavement defect and underground cavity.

Product features：

a) Large dynamic range of system design ensures and increases the detection depth of GPR, benefiting from the unique antenna design and impedance matching technique, direct data acquisition technique of ultra-wideband (UWB) signal, Synchronous time-varying auto gain control (AGC) technique of the UWB signal.

b) UWB RF switch technique in nanoseconds, can eliminate the influence of the strong reflection from the ground surface, which can enhance and improve the detection capacity of the weak reflected signal from the subsurface targets.

c) Accurate different layer detection and thickness estimation algorithm, can provide a fast, high-quality and high-accuracy detection and recognition of pavement situation.

d) Fast and automotive detection algorithm of the subsurface targets, can improve the operation efficiency of GPR.

e) high-resolution 3D imaging algorithm, can display directly the detection results.

Applications：

a) Quality assessment of the municipal projects such as great dam, bridge and express way.

b) Cavity and crack detection beneath the pavement and inside the building.

c) Location of the buried pipelines.

d) Geological engineering survey, coal mine well survey, peat survey.

e) Historical site discovery.

f) UXO and mine detection in military.
