Target characteristics and high frequency scattering mechanism are summarized. RCS analysis methods, RCS reduction approaches and low RCS target detection techniques are discussed.

A method to solve the scattering acoustic field of complex target was proposed for the near-field scattering characteristics of an underwater target in high-frequency.

In this paper, I present three studies on high-frequency seismic attenuation and propose that the physical mechanism results from the interference of elastic microscopic multiple scattering waves.
