A HRRP Recognition Method Based on KFD

2006 8th international Conference on Signal Processing, 2006
High resolution range profiles (HRRP) could accurately reflect the structure of target, so it is an important method for radar target recognition. Kernel Fisher discriminant (KFD), which is a machine learning method based on kernel function, is suitable for classification of high dimensional samples which couldn't be separated by linear classifier.

A Novel Algorithm for HRRP Target Recognition Based on CNN

2020
Compared with traditional methods, deep neural networks can extract deep information of targets from different aspects in range resolution profile (HRRP) radar automatic target recognition (RATR). This paper proposes a new convolutional neural network (CNN) for target recognition based on the full consideration of the characteristics (time-shift ...

The Radar Echo Simulation of Moving Targets Based on HRRP

2013 IEEE International Conference on Green Computing and Communications and IEEE Internet of Things and IEEE Cyber, Physical and Social Computing, 2013
To solve the radar echo simulation of moving targets, a new method is put forward based on the high resolution range profile (HRRP) of the target in this paper. Although this method demands much storage, it avoids the complicated parameter estimation, and is more close to the scattering features of target.

An infinite classification RBM model for radar HRRP recognition

2017 International Joint Conference on Neural Networks (IJCNN), 2017
High resolution range profile (HRRP) recognition is a widely used technique in the radar automatic target recognition community. However, the recognition performance often suffers from aspect sensitivity and the unsuitable features designed in practical applications.

Range-Spread Target Detection using Consecutive HRRPs

IEEE Transactions on Aerospace and Electronic Systems, 2011
In this paper, a heuristic detector is proposed to detect range-spread targets in white Gaussian noise using multiple consecutive high- resolution range profiles (HRRPs) received from a high-resolution radar (HRR). The detector consists of refiners of HRRPs and a cross-correlation integrator of refined HRRPs.

Polarization Radar HRRP Recognition Based on Kernel Methods

2009
Although the multi-polarized high resolution range profiles (HRRP) include more target information than single-polarized HRRP, the recognition becomes more difficult because of the huge data and the complex data distribution. Kernel methods based on the multi-polarized HRRPs are proposed in this paper.

Adaptive statistical model for radar HRRP recognition

IET Conference Publications, 2009
Radar automatic target recognition (RATR) should have a robust recognition performance in different noisy conditions. Most of the algorithms in RATR are based on high signal-to-noise (SNR) condition, not consider the recognition performance in low SNR.

A spatiotemporal model for radar HRRP sequence recognition

2010 IEEE Radar Conference, 2010
A temporal factor analysis (TFA) model which can describe both the spatial structure and temporal dependency of high range resolution profiles (HRRP) has been proposed for radar HRRP sequence recognition. Variational Bayes method and Bayesian classifier are adopted for model learning and classification task, respectively. The favorable results based on

A whole scheme for aircraft target identification in HRRP

2008 International Conference on Communications, Circuits and Systems, 2008
This paper describes the authorspsila efforts in practical high resolution range profile target automatic recognition. The practical high resolution range profile has more difference to simulation results, so this paper presents a novel algorithm to detect and extract the target range profile data and also create a whole scheme to deal with this ...

A New Compensation Method of HRRP for Ballistic Targets

Advanced Materials Research, 2013
The influence on the high range resolution profile (HRRP) of the ballistic target caused by high speed motion is analyzed based on the wideband radar de-chirping echo. According to the characters of ballistic target echo ambiguity diagram (AD), the auto-terms line of echo ambiguity function is extracted from the corresponding binary image by skeleton ...
