Recent improvements in speed of electronic components has led, and is leading, to improvements in both the speed and quality of GPR data acquisition. A better understanding of effect of antenna polarization and the use of multiple antennas has led to better data quality in terms of how the earth is sampled to detect and image targets. Nearly all GPR systems in the world are pulsed transmitter systems but stepped frequency continuous wave systems are being tested and may lead to improved results at least under certain conditions.
