1. A system for detecting and profiling geophysical structures and/or properties, comprising:
- an impulsive seismic source; and
a sensing means for sensing data that are representative of a plurality of echoes returned by said geophysical structures and/or properties;
wherein said impulsive seismic source generates a coded sequence of time-coded pulses;
wherein said sequence of coded pulses propagates to said geophysical structures and/or properties, causing said geophysical structures and/or properties to return said plurality of echoes; and
wherein each one of said sequence of coded pulses is a pulse in a monocycle waveform and is derived from a gaussian waveform.

Abstract
A system and method for detecting and profiling subsurface structures and/or properties. The system uses a time-coded, pulse-shaped detonation wave to impart energy to the ground. The detonation wave is a monocycle waveform. Echoes returned from geologic strata and features deep within the earth are captured and processed to localize and identify vital mineral resources such as oil or gas pockets, kimberlite pipes, salt or other concentrated mineral deposits. The system is portable and uses fuel that is both adaptable and inexpensive.
