Problems in airborne radar target recognition

Inverse Problems, 1994
A brief overview of techniques which can be applied to the problem of radar-based classification and recognition of airborne targets from airborne platforms is presented. Of particular interest are applications of radar tracking and identification methods to small airborne missile systems.

Basic Study of Navigator's Recognition of Radar Target Direction

2006 IEEE International Conference on Systems, Man and Cybernetics, 2006
The radio detection and ranging (radar) is one useful instrument which a navigator uses to attempt safe navigation in poor visibility and night navigation. In the case of poor visibility and/or many similar targets in a close area, navigators sometimes make an error in recognizing the direction when they find the target in the landscape from radar ...

Recursively partitioning neural networks for radar target recognition

IJCNN'99. International Joint Conference on Neural Networks. Proceedings (Cat. No.99CH36339), 2003
Conflicting information in the training data is responsible for most of the problems experienced by the backpropagation algorithm during network training. The self-partitioning neural network (SPNN) approach has been shown to be effective in overcoming the ill effects of learning conflict that exists among the patterns of a given class.

Target-Aware Recurrent Attentional Network for Radar HRRP Target Recognition

Signal Processing, 2019
Abstract In this paper, we develop a Target-Aware Recurrent Attentional Network (TARAN) for Radar Automatic Target Recognition (RATR) based on High-Resolution Range Profile (HRRP) to make use of the temporal dependence and find the informative areas in HRRP, since it reflects the distribution of scatterers in target along the range dimension ...

Characterization and recognition of radar targets using multiscale edges

IEEE International Conference on Acoustics Speech and Signal Processing, 1993
A method for characterizing radar signatures using the wavelet transform is developed based on the principle of scattering centers. Scattering features represented as multiscale edges can be identified based on their Lipshitz regularity coefficients.

Radar target recognition based on fuzzy clustering

ICSP '98. 1998 Fourth International Conference on Signal Processing (Cat. No.98TH8344), 2002
A new method of recognizing the aircraft number of a radar target from a narrowband IF signal of non-coherent radar is presented. According to the received narrowband IF echo signal, its autocorrelation matrix is computed. The feature vector is the eigenvalue of the autocorrelation matrix, and the orthogonal transformation is accomplished to remove the

Radar Target Recognition Using Selective Resonance Excitation

IEICE Proceeding Series, 2015
Resonance-based radar target recognition is premised on the observation of natural resonant frequencies so that target discrimination and classification can occur. This implies the use of ultra-wideband (UWB) radar in order to excite a sufficiently wide range of target frequencies, however developing practical UWB radar systems is a significant ...

Study on radar range profiles for target recognition

Proceedings of International Radar Conference, 2002
In the high frequency region, the radar range profiles are chosen as feature detectors for target recognition. The profile is dependent on the aspect of the target. In order to make radar target recognition (RTR) more effective, the definitions of correlation length and correlation angle are given. In the frequency domain, the most important feature of

A target polarization recognition method for radar echoes

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
This paper distinguishes ship target from chaff by their difference in depolarization characteristics using fully polarized dual-channel radar which transmits vertical and horizontal polarization wave alternately and receives co-polarization and cross-polarization components simultaneously with two channels.
