Adaptive detection of distributed targets in compound-Gaussian noise without secondary data: A Bayesian approach [PDF]

, 2011
In this paper, we deal with the problem of adaptive detection of distributed targets embedded in colored noise modeled in terms of a compound-Gaussian process and without assuming that a set of secondary data is available.The covariance matrices of the ...

Overview and Prospects of Radar Sea Clutter Measurement Experiments

Leida xuebao, 2019
In complex marine environments, sea clutter greatly affects the detection performance of maritime targets. Because the influencing factors of sea clutter are numerous and the mechanism is complex, there are great difficulties in feature description and ...

Chaotic modelling of sea clutter

Electronics Letters, 1992
In the letter we present calculations based on experimental radar data which confirm the chaotic nature of sea clutter. In particular, the results of the calculations show that the first Lyapunov exponent of sea clutter is indeed positive and around 0.015. Such a result is an inherent characteristic of a chaotic process.
