Supports land and water detection. Requirements: Transmission frequency not lower than 600kHz, A/D conversion not lower than 16 bits, scanning rate not lower than 1000 lines/s, and sampling points not lower than 10,000 points.
(1) Host:
Industrial integrated real-time acquisition processor host, powered by a built-in lithium battery, eliminating the need for an external operation terminal during data acquisition. The host can accommodate all high, medium, and low-frequency probes, with a compatible probe frequency range: low-frequency lower limit not higher than 16MHz, and high-frequency upper limit not lower than 2600MHz; the host can be connected to an analog antenna via coaxial cable or to a digital antenna via network cable in a digital signal manner; scanning sample point counts: 256/512/1024/2048/4096/8192/16384. Gain: manual or automatic; advanced real-time filter: equipped with effective signal bottom tracking function, offset, and surface signal displacement tracking; host transmission rate: ≥800kHz; acquisition and display methods: the host must incorporate a three-dimensional data acquisition mode, enabling three-dimensional data processing and display on the host, including display of slice images and three-dimensional stereo images; display modes: line scan, line scan + waveform, waveform plus variable area, and full 3D display; host language: supports Chinese and English.
(2) Probes and cables
consist of multiple frequencies ranging from 10MHz to 100MHz, allowing for the selection of probes with different frequencies according to the detection depth and site conditions;
data transmission between the probe and the host is conducted via coaxial cables, which are sturdy, durable, and have strong soil and dust resistance, not subject to environmental constraints.
(3) Post-processing software requirements
The post-processing software supports Chinese and English interfaces; the software offers a diverse selection of modules, including basic data processing, dam and embankment, municipal pipelines, culverts, and other surveys, as well as three-dimensional slice module analysis.
