This book provides an authoritative account of the current understanding of radar sea clutter@ describing its phenomenology@ EM scattering and statistical modelling and simulation@ and their use in the design of detection systems and the calculation and practical evaluation of radar performance. The book pays particular attention of the component K distribution model developed by the authors during the past 20 years. The evidence for this model@ its mathematical formulation and development and practical application to the specification@ design and evaluation of radar systems are all discussed. In addition@ the book sets the previously empirical development of the K distribution model in the wider context of recent advances in the calculation of low grazing angle electromagnetic scattering and oceanographic modelling of the statistics of the sea surface.
