Abstract

We are developing an innovative low-noise directional borehole radar system. Harsh and changing operating environments are a challenge to the low-noise sensitive electronic design. Additionally a system with such high sensitivity is susceptible to temperature changes and to component parameter variations. Therefore a calibration module was developed to calibrate the overall measurement system with a test signal generator. This calibration includes channel matching for accurate direction detection and sampling clock correction. After a brief introduction, testing and calibration methods are introduced. Additionally measurement results and figures depicting the practical results achieved thus far are included.
