A NUFFT Based Step-frequency Chirp Signal High Resolution Imaging Algorithm and Target Recognition Algorithm

Leida xuebao, 2015
Radar Automatic Target Recognition (RATR) is the key technique to be breaked through in the fuure development of intelligent weapon system. Compared to the 2-D SAR image target recognition, High Resolution Range Profile (HRRP) target recognition has the ...

Synthetic UWB Range Profile Using SFPTs and Class MUSIC for High-resolution Velocity Estimation

, 2012
A method, called class multiple signal classification (CMUSIC), is proposed to estimate high-resolution radial velocity in each pulse train (subband, i.e. narrowband) with M pulses based on stepped frequency pulse trains (SFPTs) signal. A synthetic ultra-

Polarised HRRP scattering centre estimation via atomic norm minimisation

The Journal of Engineering, 2019
The combination of polarisation and high-resolution technology is a promising research direction for radar automatic target recognition. Fusing the polarisation information into the scattering centre model is able to refine the scattering structural ...

Radar High-Resolution Range Profile Ship Recognition Using Two-Channel Convolutional Neural Networks Concatenated with Bidirectional Long Short-Term Memory

, 2021
Radar automatic target recognition is a critical research topic in radar signal processing. Radar high-resolution range profiles (HRRPs) describe the radar characteristics of a target, that is, the characteristics of the target that is reflected by the ...

A novel HRRP target recognition method based on LSTM and HMM decision-making [PDF]

, 2019
Feature learning is a key step of target recognition for high-resolution range profile (HRRP). In traditional methods, Hidden Markov Model (HMM) can learn the features of HRRP target aspect information.

Point-HRRP-Net: A Deep Fusion Framework via Bi-Directional Cross-Attention for Space Object Classification Using HRRP and Point Cloud

Remote Sensing
High-Resolution Range Profile (HRRP)-based space object classification is severely limited by aspect sensitivity. Inspired by the intrinsic complementarity between HRRP and LiDAR point clouds, this work investigates the feasibility and effectiveness of ...

Localization of Jet Engine Position from HRRP-JEM Images of Aircraft Targets Using Eccentricity of Complex-Valued Signals

, 2013
2005년에 처음 소개된 HRRP-JEM(High Resolution Range Profile-Jet Engine Modulation) 영상은 항공기 표적에 탑재된 제트 엔진의 장착 위치를 추정함으로써 레이더 표적 인식을 수행한다. 본 논문에서는 복소 신호의 이심률을 기반으로 HRRP-JEM 영상에서 제트 엔진 위치를 추정하기 위한 새로운 접근법을 제시한다. 복소 신호의 이심률은 HRRP-JEM 영상을 구성하는 어떤 거리 성분(range bin)에서의
