Abstract
An object detection system may be capable of sensing a buried object and providing an estimate of the object's depth. The object detection system may comprise a signal generator transmitting one or more signals. At least one of the signals may be directed toward the buried object and reflected off of the object back to the system. At least one of the signals may be transmitted along a variable length path. A correlator may then receive the signals and determine an offset between their arrival times at the correlator. The variable length path may then be adjusted over a range which includes a minimum offset indicating a distance to the object.
Claims18
An object detection system, comprising:
- a random signal generator transmitting one or more random continually varying analog signals;
- at least one of the random continually varying analog signals transmitted along a variable physical-distance path comprising a length of wire;
- at least one of the random continually varying analog signals directed toward an object and reflected by the object;
- a correlator receiving at least two of the random continually varying analog signals;
- an offset between arrival times of the at least two random continually varying analog signals received by the correlator;
- and
- wherein the variable physical-distance path is adjustable over a range which includes a minimum offset indicating a distance to the object.
