© 2003 Society of Exploration Geophysicists. The detection and discrimination of buried metal targets is an important aspect of geophysical electromagnetic induction (EMI) techniques. A Geonics EM63 time domain metal detector was modified from its standard configuration to permit variable transmitter-receiver (TX-RX) offsets. Several aluminum and steel objects were buried in shallow ground. Transient electromagnetic responses were measured and are presented in profile and map forms. The responses from different target arrangements show distinctive spatiotemporal RX induced-voltage patterns. The results indicate that pattern recognition methods may be useful for buried metal target discrimination using multi-RX EMI array configurations.
