Remote Sensing, 2015 We propose a constant false alarm rate (CFAR) algorithm for moving target detection in synthetic aperture radar (SAR) images based on the spreading characteristics of interferograms on the magnitude-phase (M-P) plane.

GLRT‐based compressive subspace detectors in single‐frequency multistatic passive radar systems
IET Radar, Sonar & NavigationThe authors study the problem of compressive target detection in a single‐frequency network (SFN)‐based multistatic passive radar system (MS‐PRS) consisting of multiple illuminators of opportunity (IOs) and one receiver. Firstly, a generalised likelihood

The Geometry of Signal Detection with Applications to Radar Signal Processing
Entropy, 2016 The problem of hypothesis testing in the Neyman–Pearson formulation is considered from a geometric viewpoint. In particular, a concise geometric interpretation of deterministic and random signal detection in the philosophy of information geometry is ...

Radar target detector based on banded sample autocovariance matrices
EURASIP Journal on Advances in Signal ProcessingDetecting weak radar targets in complex cluttered environments remains a significant challenge, particularly when attempting to effectively detect low signal-to-clutter ratio (SCR) targets while maintaining a constant false alarm rate (CFAR).

Closed-Form Solution for CFAR Detection Threshold in G0 Distributed SAR Clutter
IEEE AccessWe devise a constant false alarm rate (CFAR) detector for detecting targets in clutter regions with varying degrees of heterogeneity. The CFAR detector employs the $\mathcal {G}^{0}$ distribution for characterizing the statistics of background ...
