recommendations! Published in 2019 at "Marine Geodesy"

DOI: 10.1080/01490419.2019.1692265

Abstract: Abstract Seafloor terrain and water column target detection is of great significance in marine surveys. However, the complex clutter environment can dramatically affect the detection performance of a multi-beam echo sounder. To simultaneously and robustly… read more here.

DOI: 10.1080/2150704x.2020.1744043

Abstract: ABSTRACT In this paper, the zlog(z) based estimator for constant false alarm rate (CFAR) detection in Weibull clutter is proposed. This estimation method is obtained in terms of the digamma function where the estimates of… read more here.
