The range alignment algorithm for high-resolution range profile of multiple target

2016 11th International Symposium on Antennas, Propagation and EM Theory (ISAPE), 2016
Aiming at the problem of the difficulty in the range alignment of HRRP because of more than one target in the window of radar image, this paper propose a alignment method for multiple targets in the target group by using an image segmentation method. First, we accumulate the HRRP of the target, and get the HRRP process diagram.

RADAR TARGET RECOGNITION BASED ON PARAMETERIZED HIGH RESOLUTION RANGE PROFILES

International Journal of Pattern Recognition and Artificial Intelligence, 2000
A new scheme of radar target recognition based on parameterized high resolution range profiles (PHRRP) is presented in this paper. A novel criterion called generalized-weighted-normalized correlation (GWNC) is proposed for measuring the similarity between PHRRP's.

Maritime ATR using Classifier Combination and High Resolution Range Profiles

IEEE Transactions on Aerospace and Electronic Systems, 2011
A maritime automatic target recognition system is developed that performs ship classification using one-dimensional high resolution range profiles. Five physically based features are defined and are extracted from both VV and HH polarizations resulting in a 10-dimensional feature vector.

Features for high resolution radar range profile based ship classification

ISSPA '99. Proceedings of the Fifth International Symposium on Signal Processing and its Applications (IEEE Cat. No.99EX359), 2003
This study investigates a variety of features in the context of automated ship classification of high resolution radar range profile. The features used are length, scatterer count, centres of mass, quantised range profile and Fourier modified direct Mellin transform coefficients.

Properties of high-resolution range profiles

Optical Engineering, 2002
Wideband radar can obtain much target information due to its high-range resolution. Because its size is smaller than the resolution of conventional radar, for an airplane, it can be regarded as a point. However, for wideband radar with a bandwidth of several hundred megahertz, the range resolution is less than a meter, and airplane echoes of one ...

Performance analysis of radar high-resolution range profiling for stationary targets

2017 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2017
The high-resolution range (HRR) profile is an important performance indicator for modern radars. In this paper, we discuss the problems associated with radar HRR profiling of stationary targets, including the profiling ambiguity, stability, and accuracy.

High resolution range profile with promoted sparsity and refined grid

IET International Radar Conference 2013, 2013
A high resolution range profile (HRRP) method via compressed sensing (CS) with re-weighted 11 minimization is proposed. Since the weighted CS model has a better representation of the true sparse description than that of the general 11 norm based CS model, the proposed compressive HRRP exhibits a remarkable suppression of the noise influence when ...

Automatic target recognition using sequences of high resolution radar range-profiles

IEEE Transactions on Aerospace and Electronic Systems, 2000
In this paper, we address the problem of joint tracking and recognition of a target using a sequence of high resolution radar (HRR) range-profiles. The likelihood function for the scene configuration combines a dynamics-based prior on the sequence of target orientations with a likelihood for range-profiles given the target orientation.

High-resolution range profile

2005
In this chapter high-range resolution radar is presented. A high-resolution range profile (HRRP) is a one-dimensional signature of an object. It is a representation of the time domain response of the target to a high-range resolution radar pulse.
