GEOPHYSICAL SURVEY SYSTEM

摘要

A geographical survey system for obtaining, recording and displaying data in near real-time at a survey site. The system comprises a sensor system comprising at least one metal detector for detecting buried metal objects such as unexploded ordnance or land mines. A movable sensor platform supports the metal detector at a desired height above the ground. A support vehicle tows or pushes the sensor platform along the ground at the survey site, and comprises a geo-reference system for locating a reading from the metal detector relative to the earth, a power source for the sensor system and geo-reference system, and computer hardware and software for controlling the collection of, storing, displaying and analyzing data from the sensor system and the geo-reference system. A control unit is provided on the support vehicle for regulating the power supply from the power source thereon to the sensor system and the geo-reference system to ensure substantially uniform power to an accurate operation thereof.
