title = "Nonlinear acoustic landmine detection",
abstract = "Numerous field tests have demonstrated that buried landmines manifest themselves at the surface through linear and nonlinear responses to acoustic/seismic excitation at the frequencies below 1000 Hz. The linear signatures are due to lower impedance of soil above {"}softer{"} mine, especially in the vicinity of mine's resonance. These phenomena are utilized for landmine detection demonstrating high provability of detection and low false alarms. The paper provides overview of theoretical and experimental investigations conducted by the author and his colleagues at Stevens Institute of Technology with emphasis on the nonlinear detection. Among major accomplishments are development of a simple engineering model explaining and predicting the nonlinear soil-mine dynamic behavior; analysis of the nonlinear acoustic interactions at the soil-mine interface; development and field validation of nonlinear quadratic and intermodulation detection algorithms based on dual-frequency excitation.",
