High Resolution Range Profile Recognition Using Robust Kernel Neighborhood Preserving Projection

2012 IEEE 12th International Conference on Computer and Information Technology, 2012
A new manifold learning algorithm, called robust kernel neighborhood preserving projection (RKNPP), is presented and applied to radar target recognition based on high resolution range profiles. RKNPP attempts to map the high-dimensional data into such a low-dimensional space where points belonging to the same class are close to each other while points ...

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.

Radar high-resolution range profile target recognition with hyperparameter self-learning

2019 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2019
A hyperparameter self-learning method is developed for radar high-resolution range profile (HRRP) target recognition, which searches for the best hyperparameters based on the current data for preprocessing and feature extraction. Exploring the correlation between hyperparameters, our method achieves the optimum of parameter collocation with ...

Aerial Target Recognition Based on High Resolution Range Profiles (HRRP)

2014
The fact that very small aspect changes can drastically alter the profile of an aircraft implies that a huge number of profiles would be required to characterize an aircraft from all possible aspects. This make a look-up table approach to classification impractical in the short-wavelength limit.

High-resolution range profile synthesis based on a new radar waveform

2016 CIE International Conference on Radar (RADAR), 2016
A new waveform for high-resolution range profile synthesis with flexible bandwidth scalability is proposed in this paper. Its ambiguity function and frequency spectrum characteristics are spelled out. The signal employs a bounded function in the time domain to broaden bandwidth with time linearly.

Bayes-optimality based feature transform for high resolution range profile identification

6th International Conference on Signal Processing, 2002., 2003
Many feature transform methods have been used for radar target identification. But most of them are based on scatter matrices or other statistics of the data, which do not directly correlate to classification accuracy. In this paper, a Bayes-optimality based adaptive feature transform method is proposed for radar target identification using high ...

A Dual-Polarimetric High Range Resolution Profile Modulation Method Based on Time-Modulated APCM

IEEE Transactions on Antennas and Propagation
The discovery of electromagnetic (EM) metasurfaces has significantly advanced the free manipulation of EM waves. Furthermore, the harmonic phenomena based on time-modulated metasurfaces (TMMs) have received much attention in communication and radar ...

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.

OTFS-Based ISAC for Super-Resolution Range-Velocity Profile

IEEE Transactions on Communications
The recently popularized ISAC paradigm attempts carry out both communication and sensing functionalities uses the same time-frequency resources to combat the scarcity of these resources. However, high-resolution range and velocity radars require wideband
