ADOS-CFAR Algorithm for Multibeam Seafloor Terrain Detection

International Journal of Distributed Sensor Networks, 2016
To solve the false terrain problem caused by the tunnel effect in the conventional multibeam seafloor terrain detection, a detection method of multibeam seafloor terrain based on the ADOS-CFAR (Amplitude Dichotomy Order-Statistics Constant False Alarm ...

Research on a New Comprehensive CFAR (Comp-CFAR) Processing Method

IEEE Access, 2019
Since the clutter statistics of marine radar are non-stationary and difficult to ascertain, the constant false-alarm rate (CFAR) processor based on some clutter statistical characteristics is hard to obtain the CFAR performance.

Detecting flying objects in synthetic aperture radar images using Moving Target Indicator methods

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper presents a moving target indicator detection method (MTI) for detecting planes during take‐off in synthetic aperture radar data, and a theoretical ground‐clutter suppression method via cross‐track interferometry to detect airborne targets. The MTI method combines interferometric processing, acceleration compensation, and autofocus techniques.
