Resolution independent radar target recognition

2011 IEEE RadarCon (RADAR), 2011
The value of Through the Wall Radar Imaging (TWRI) data collected with one system is limited when training the automatic target recognition classifier of a second system because of variation in the Point Spread Function (PSF). The target image is a function of both the scene reflectivity and the PSF, which is in turn a function of the imaging radar's ...

A fractal approach to radar target recognition

Proceedings of International Radar Conference, 2002
A method of radar target classification and recognition through extracting their fractal features directly from the radar echoes is presented. Firstly, two dimensional texture images with distances and directions as the coordinate axes are formed, then, the FFT-Mellin transformation is applied to eliminate the affect caused by flights' motion, posture ...

CMAC-based radar target recognition

Proceedings 2011 International Conference on System Science and Engineering, 2011
Radar plays a crucial role in the modern electronic warfare. The identification of radar types, parameter information, platform features, and operation conditions all contribute to a commander's decision-making process. However, as a traditional electronic intelligence reconnaissance system (ELINT) relies on merely one single platform with built-in ...

Correlation target recognition for laser radar

SPIE Proceedings, 2006
The target recognition of laser radar is a hot research because laser radar can produce the intensity and range imagery. Laser radar has high space resolution, and can obtain rich target information. Correlation recognition has been used to many fields, such as infrared as well as synthetic aperture radar (SAR).

Reconstruction and recognition of the radar target image

5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service. TELSIKS 2001. Proceedings of Papers (Cat. No.01EX517), 2002
A method for generating the spatial image of several types of jets is presented. The method consists in applying the Radon transform to a data set containing discrete values of the frequency characteristic of the objects under study, for several illumination angles. A Matlab program was developed for image reconstruction.

One-Shot HRRP Generation for Radar Target Recognition

IEEE Geoscience and Remote Sensing Letters, 2022
Insufficient data of a noncooperative target seriously affect the performance of radar automatic target recognition (RATR) using the high-resolution range profile (HRRP), especially when the noncooperative target has only one sample. To this end, we propose an unsupervised data generation method to generate noncooperative HRRP signals.

Radar target recognition by probabilistic filtering

SPIE Proceedings, 2004
The paper presents a new method of probabilistic filtering for radar target recognition. The classical Bayesian detector/estimator suffers from the insufficient information about target signature probability distributions and their a priory appearance probabilities. If the number of radar image objects to be classified is not known exactly the appeared

Statistical Modeling With Label Constraint for Radar Target Recognition

IEEE Transactions on Aerospace and Electronic Systems, 2020
Motivated by the problem of radar target recognition, we develop a label-aided factor analysis (LA-FA) model for statistical modeling of high-resolution range profile (HRRP) under the prerequisite that the HRRP data are Gaussian distributed. The LA-FA model is the extension of the multitask learning-based factor analysis (MTL-FA) model, which is mainly

Application of function link net to recognition of radar targets

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
This paper studies the mechanism for classification of feedforward neural networks from the geometric viewpoints. It is pointed out that the multilayer perceptron networks (MLPNs) realize hyperplane divisions in the pattern space, and the FLN realize hypercurved divisions.
