A method of range measurement based on high resolution range profile

2017 11th European Conference on Antennas and Propagation (EUCAP), 2017
In conventional methods, the weighted mean range of the scattering centers on the high resolution range proflle(HRRP) is assumed as the range between the target center and radar. However, this assumption is not reasonable because the scattering center with the maximum amplitude may not locate at the center of the target.

The Range Alignment Algorithm for High-Resolution Range Profile Based on Image Segmentation

2016 International Conference on Identification, Information and Knowledge in the Internet of Things (IIKI), 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.

Polarization identification of high resolution range profiles

Proceedings of the IEEE 1995 National Aerospace and Electronics Conference. NAECON 1995, 2002
In this paper, a novel effective polarization identification method is presented for vehicle sized ground target identification application. The method uses wide band FMCW orthogonal duel-polarization technology to obtain the degraded PSM of each scattering center in high resolution range profile.

Bistatic high-range resolution profiles of wobbling targets

IET International Radar Conference 2015, 2015
This study considers how to utilize the high range resolution profiles (HRRPs) of wobbling targets for feature extraction. The movement model of wobbling targets and the bistatic HRRP model are introduced firstly. Based on the bistatic HRRPs of the wobbling target simulated via the bistatic scattering coefficients obtained via electromagnetic ...

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 ...

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.

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.
