Ship 3D model estimation from an ISAR image sequence

Moving Target Analysis in ISAR Image Sequences With a Multiframe Marked Point Process Model

“…Therefore, by using ISAR image sequences, such shortcomings may be overcome. Sequences of ISAR images have been used previously to improve both ISAR image formation (even allow reconstructing 3D ISAR images [5]) and target's classification and recognition [6]. Other important aspects related to classification is the resemblance between features extracted from the ISAR image under test and those present in the database.…”

“…A number of ATR techniques based on sequences of ISAR images have been proposed in the literature. Some of them directly utilize the 2D ISAR frames [4], whereas others attempt a 3D image reconstruction before dealing with the classification problem [5], [6]. However, robust feature extraction and feature tracking in the ISAR images are usually difficult tasks due to the high noise factors and low level of available details about the structure of the imaged targets.…”

Ship dynamics for maritime ISAR imaging.

“…The collected data is present over a 3-D volume." Cooke 23 further describes a "numerical algorithm for retrieving 3-D scatterer locations and ship motion parameters from a series of Doppler measurements extracted from ISAR imagery." …”

ISAR image sequence based Automatic Target Recognition by using a Multi-Frame Marked Point Process model

“…A number of ATR techniques based on sequences of ISAR images have been proposed in the literature. Some of them directly utilize the 2D ISAR images [3], whereas others attempt a 3D signal reconstruction before dealing with the classification problem [4,5]. Due to the physics of ISAR imaging, consecutive images of an ISAR sequence may have significantly different quality in terms of image focus.…”
