Synthetic Aperture Radar Target Recognition with Feature Fusion Based on a Stacked Autoencoder

Feature extraction is a crucial step for any automatic target recognition process, especially in the interpretation of synthetic aperture radar (SAR) imagery. In order to obtain distinctive features, this paper proposes a feature fusion algorithm for SAR target recognition based on a stacked autoencoder (SAE). The detailed procedure presented in this paper can be summarized as follows: firstly,...

Feature matching and target recognition in synthetic aperture radar imagery

An approach for target matching in Synthetic aperture radar (SAR) imagery is presented. The method is feature based where feature points in a target candidate are matched against those from an exemplar database. Matching is formulated as a non-linear optimization problem that encourages matches while minimizing the distance between the matched features. The formulation allows for missing, spuri...

Model-based Bayesian feature matching with application to synthetic aperture radar target recognition

We present a Bayesian approach for model-based classi"cation from unordered, attributed feature sets. A set of features is estimated from measured data and is matched with a set predicted for each candidate hypothesis using a feature model. Both extracted and predicted feature sets have uncertainty, and some features may not be present in one set or the other. Computation of the match likelihoo...

Radar HRRP Target Recognition Based on Stacked Autoencoder and Extreme Learning Machine

A novel radar high-resolution range profile (HRRP) target recognition method based on a stacked autoencoder (SAE) and extreme learning machine (ELM) is presented in this paper. As a key component of deep structure, the SAE does not only learn features by making use of data, it also obtains feature expressions at different levels of data. However, with the deep structure, it is hard to achieve g...
