The use of ground-penetrating radar with a cooperative target

Abstract

A cooperative target (CT) is proposed to enhance the ground-penetrating radar (GPR) signal-to-clutter ratio (SCR) for buried man-made targets. Applications include tagging high-value buried structures and monitoring microtunneling equipment. Results are presented for a time-domain CT, a dipole antenna connected to an unterminated delay line. By using several independent time-domain CTs, strategically arrayed about a target, the rotational aspect of the target can also be obtained. Finally, harmonic generation is demonstrated as a technique for a frequency-domain CT.
