Terahertz High-resolution Radar Clutter Measurement and Analysis
Leida xuebao, 2015 The clutter characteristics of terahertz high-resolution radar are essential for terahertz radar detection. This study analyzes the traditional clutter probabilistic model and the corresponding parametric estimation methods.

Modeling the Amplitude Distribution of Radar Sea Clutter [PDF]
Remote Sensing, 2019 Ship detection in the maritime domain is best performed with radar due to its ability to surveil wide areas and operate in almost any weather condition or time of day. Many common detection schemes require an accurate model of the amplitude distribution of radar echoes backscattered by the ocean surface. This paper presents a review of select amplitude

Radar small/mini target detection technology in strong clutter environment
The Journal of Engineering, 2019 A method of radar small/mini target wavelet transform and principal component analysis in strong clutter environment is suggested. Focusing on the situation that the small/mini target in the strong clutter environment is swamped by clutter, traditional ...
