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:

- 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.
