Abstract:
1. A movable sensor apparatus, comprising: a movable housing; at least one supporting extension wherein each said supporting extension is rotatably affixed to said housing, being fully rotatable about a first axis; at least one sensor for sensing an object buried beneath a surface of the earth, wherein each at least one sensor is rotatably affixed to one of said at least one supporting extension and is fully rotatable about a second axis substantially parallel to and offset from said first axis so as to scan an area of the surface of the earth; a linear propulsion mechanism attached to said housing whereby said housing may be moved over the ground; a mechanism to fully rotate each at least one supporting extension about the first axis and to fully rotate each at least one sensor about the second axis, so as to cause the at least one sensor to scan the area of the surface of the earth as said housing moves across said area; a triggering unit electrically coupled to each of said at least one sensor and capable of separately activating each of said at least one sensor; and a sampling unit electrically coupled to each of said at least one sensor and capable of receiving output from each of said at least one sensor.
