1. An underground drilling device for use with an above-ground locator, comprising:
- a cutting tool assembly comprising a cutting tool and a sensor housing;
a radar unit provided in the sensor housing;
a transmitter provided in the sensor housing; and
a processor provided in the sensor housing and communicatively coupled to the radar unit and the transmitter, the processor receiving radar data from the radar unit and producing sensor data for transmission via the transmitter in a form suitable for reception by the above-ground locator.

Abstract
Systems and methods for sensing at an underground drilling device in communication with an above-ground locator involve transmitting a radar probe signal from the underground drilling device. A radar return signal is received at the underground drilling device. The radar return signal is processed at the underground drilling device to produce sensor data. The sensor data is transmitted in a form suitable for reception by the above-ground locator.
