Dual
Technologies
The AN/PSS-14 combines wide band, ground-penetrating radar with an extremely sensitive metal detector.
Ground
Penetrating Radar
The GPR for the device is based on a wide-band, coherent,
stepped frequency radar transceiver. The search head contains
one transmit and two receive antennas. The transmit antenna
produces continuous wave, low power radar. When these waves
strike a discontinuity such as a mine, rock, root, air pocket,
combat debris, pipes or cables, some are reflected back
to the two receive antennas and processed by the system.
Advanced
Metal Detector
The metal detector consists of a flat annular coil that
encompasses the entire diameter of the sensor head. Passing
current through the coil and transmitting into the soil
creates an electromagnetic field that induces electrical
current in any metal object that might be buried in the
soil. The metal object then produces its own electromagnetic
field that is transmitted back to the coil in the sensor
head. The sensor head detects this electromagnetic field
and responds with an alarm, alerting the soldier to the
presence of a possible mine even when it has been fabricated
with minimal metal parts.
