GEORADAR

PURPOSE:

To monitor the condition of roads.

ADVANTAGES:

Unlike existing analogs: decoupling, signals from the emitter are attenuated at the receiver input by -65 dB, the amplitudes of useful signals increase; variable readout duration and optimization increase signal-to-noise ratio; high stability of synchronization contributes to the accumulation of signals; analog accumulation at reception expands the operating frequency band and increases the signal-to-noise ratio. Improved energy performance increases sounding depth, localization accuracy of subsurface objects and detection of low-contrast objects.

TECHNICAL CHARACTERISTICS:

    • Collects data at speeds up to 70 km / h in 23 cm.
    • Pulses that probe:
      • amplitude, V> = 75.
      • pulse rise time, ns <= 0.4.
    • Antenna:
      • working frequency band, GHz 0.8-1.6.
    • Receiver:
      • noise level, μV <= 200.
      • reading step, ps 10.
      • rise of the transient response, ns <= 0.2.
      • read synchronization error, ps <3.
    • Observation intervals, μs <= 2.

RECOMMENDED FIELD OF APPLICATION:

Road industry.
