A hierarchical HRRP(k) network and its application

Peer-to-Peer Networking and Applications, 2014
This paper is concerned with the problem of how to share distributed resources. As an application of distributed resource sharing in schools, a peer-to-peer network model (HRRP(k)) is proposed and its properties are studied. It is proven that HRRP(k) network has better performance than a 2-D mesh in group communication.

Recognition-Aware HRRP Generation With Generative Adversarial Network

IEEE Geoscience and Remote Sensing Letters, 2022
Existing works on radar high-resolution range profile (HRRP) recognition commonly focus on utilizing data and various deep learning models in achieving high classification accuracy. However, in practical applications, it is often difficult to obtain HRRP signals, especially for noncooperative targets.

Aircraft HRRP classification based on RBFNN

2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559), 2002
We present a classification scheme based on a new kind of RBFNN (radial basis function neural network) whose structure is similar to that of AWNN (adaptive wavelet neural network). To be more suitable for HRRP (high resolution range profile) classification, this kind of RBFNN substitutes wavelet basis functions in AWNN with Gaussian basis functions. In

An algorithm based on HRRP for target recognition

2011 International Conference on Image Analysis and Signal Processing, 2011
Based on the scattering center model, the dissertation makes detailed analysis on the physical property of HRRP samples and points out the HRRP sensitivity of target-aspect. The average HRRP for feature extraction is presented in a small target-aspect after the HRRP preprocessing methods are discussed, and experiment results based on the SVM classifier

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.

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.

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.
