Earth penetrating apparatus and method employing radar imaging and rate sensing
First Claim
1. An earth penetrating apparatus for use with a boring machine, comprising:
- a cutting tool assembly comprising a cutting tool and a sensor housing;
a radar unit provided in the sensor housing;
an antenna arrangement coupled to the radar unit, the anterina arrangement configured for transmitting and receiving electromagnetic signals in a relatively forward looking direction relative to a distal end of the cutting tool;
a rate sensor unit provided in the sensor housing, the rate sensor unit comprising one or both of a gyroscope and an accelerometer;
a processor provided in the sensor housing and communicatively coupled to the radar unit and the rate sensor unit, the processor receiving radar data from the radar unit indicative of subsurface strata and obstacles respectively located generally forward of the cutting tool and receiving displacement data from the rate sensor unit indicative of one or both of longitudinal and rotational displacement of the cutting tool; and
a transmitter provided in the sensor housing and coupled to the processor, the transmitter configured for transmitting one or both of the radar data and the displacement data to an aboveground location.

Abstract
An earth penetrating apparatus includes a cutting tool and a sensor housing. A radar unit, rate sensor unit, processor, and transmitter are provided in the sensor housing. An antenna arrangement is coupled to the radar unit and configured for transmitting and receiving electromagnetic signals in a relatively forward and/or lateral looking direction relative to a distal end of the cutting tool. The rate sensor unit may include one or both of a gyroscope and an accelerometer. The processor receives radar data from the radar unit indicative of subsurface strata and obstacles respectively located generally forward and/or lateral of the cutting tool, and receives displacement data from the rate sensor unit indicative of one or both of longitudinal and rotational displacement of the cutting tool. The transmitter is configured for transmitting one or both of the radar data and the displacement data to an aboveground location.
