EM-based Solutions for Covariance Structure Detection and Classification in Polarimetric SAR Images
Pia Addabbo, Filippo Biondi, Carmine Clemente +3
This paper addresses the challenge of classifying polarimetric SAR images by leveraging the peculiar characteristics of the polarimetric covariance matrix (PCM). To this end, a gen…
Novel Parameter Estimation and Radar Detection Approaches for Multiple Point-like Targets: Designs and Comparisons
Pia Addabbo, Jun Liu, Danilo Orlando +1
In this work, we develop and compare two innovative strategies for parameter estimation and radar detection of multiple point-like targets. The first strategy, which appears here f…
Learning Strategies for Radar Clutter Classification
Pia Addabbo, Sudan Han, Danilo Orlando +1
In this paper, we address the problem of classifying clutter returns in order to partition them into statistically homogeneous subsets. The classification procedure relies on a mod…
CFAR Feature Plane: a Novel Framework for the Analysis and Design of Radar Detectors
Angelo Coluccia, Alessio Fascista, Giuseppe Ricci
Since Kelly's pioneering work on GLRT-based adaptive detection, many solutions have been proposed to enhance either selectivity or robustness of radar detectors to mismatched signa…
A k-nearest neighbors approach to the design of radar detectors
Angelo Coluccia, Alessio Fascista, Giuseppe Ricci
A k-nearest neighbors (KNN) approach to the design of radar detectors is investigated. The idea is to start with either raw data or well-known radar receiver statistics as feature…
Adaptive Radar Detection of Dim Moving Targets in Presence of Range Migration
Pia Addabbo, Danilo Orlando, Giuseppe Ricci
This paper addresses adaptive radar detection of dim moving targets. To circumvent range migration, the detection problem is formulated as a multiple hypothesis test and solved app…
