title = "Estimation of Compound K-distribution Modeling Parameters of Sea Clutter with Unknown Thermal Noise Power",
abstract = "This paper explores a new and efficient method for estimating the parameters of the compound K-distribution model of sea clutter when the thermal noise power is also unknown. Current methods for the model parameter estimation include the intensity moments approach that assumes knowledge of the thermal noise power and a three-dimensional (3-D) curve fitting approach that is very computationally intensive. The proposed method integrates the intensity moments with a nonlinear one-dimensional (1-D) curve-fitting procedure to also allow for an efficient estimate of the thermal noise power. It is also extended to incorporate fractional moments used under the condition of known clutter-to-noise ratios. The performance of the new approach is demonstrated using both simulated and real sea clutter observations.",

note = "Funding Information: We validated both NEIM and CEFM performance using sea clutter observations from a database provided by the Council for Scientific and Industrial Research (CSIR). The data was collected using the Fynmeet Radar deployed at Measurement Station 3 in the Overberg Test Range. The trials were conducted between 25 July and 4 August 2006 [18]. The radar operates with the following: 9GHz RF center frequency, 5kHz pulse repetition frequency, 15 m range resolution, and VV polarization. Funding Information: Acknowledgments We thank the South African Council for Scientific and Industrial Research (CSIR) for access to the small boat trails sea-clutter database.
