Comparison of ship detectors using polarimetric alos data: Tokyo Bay

Abstract

Ship detection with Synthetic Aperture Radar is a largely investigated topic and a series of operational algorithms are currently exploited by the users community. Polarimetry may play an important rule in this context, since the next generation of SAR satellites will be able to perform large swath polarimetric (either dual or compact) acquisitions. In this work, a comparison of promising ship detectors employing polarimetric information is performed over an ALOS-PALSAR quad-polarimetric dataset acquired over Tokyo Bay (October 2008). Interestingly, a survey of the area is available allowing to provide some quantitative comparison of the different detectors. The results show that the quad polarimetric detectors return better detection performance than the dualor single-polarimetric ones.

The InflateSAR Campaign: Developing Refugee Vessel Detection Capabilities with Polarimetric SAR

“…For such a time-critical application in disaster mitigation, synthetic aperture radar (SAR) is appropriate and practicable due to its all-weather and its 24 hour imaging capabilities. Moreover, the detection of ships and other maritime objects with SAR has a long research history (e.g., [4][5][6][7][8][9][10][11]).…”

Empirical Analysis of Ship Detection and Dimension Estimation from RISAT-1 Compact Polarimetric Data

“…Prominently assumed distributions in literature are Gaussian, K-Distribution [13], Weibull [14]. The popular ship detectors as per the literature and the frequently exploited data for this research domain are mentioned in [16], [17], [18] ALOS [19], [20], [17], [21] SENTINEL-1 [22], [15], [23], [24] RADARSAT-2 [22], [25], [26], [27], [20], [28], [29], [17] CosmoSkymed [22], [25], [30], [28] UAVSAR [26], [3] TerraSAR-X [31], [30], [29], [32], [24] RADARSAT [19], [22], [15], [30], [28], 15, [32], [21] GP-PNF [19], [31], [20] SPAN [16], [17] DoP [26] m…”

Ship Detection in PolSAR Images Based on a Modified Polarimetric Notch Filter

“…Taking a single channel from multi-channel full-polarized SAR images, ship detection can be conducted with typical approaches designed for single-polarized SAR images. In [1], Marino et al utilized the cross-polarization channel HV image to detect ships. Up to now, many approaches have been proposed for single-polarized SAR imagery, including the following: the conventional constant false alarm rate (CFAR) detector and its different versions [2][3][4][5][6], saliency detectors [7,8], and deep learning networks [9][10][11], etc.…”
