Sparse processing with range migration compensation capability for a frequency agile orthogonal frequency division multiplexing waveform

open access: yesIET Radar, Sonar & Navigation, 2022
Digital‐to‐analogue and analogue‐to‐digital in a digital array radar limits the transmission and reception of instantaneous broadband signals (IBSs), which makes it a technical bottleneck for digital array radar to obtain an instantaneous broadband high ...

Dynamic Gesture Recognition with a Terahertz Radar Based on Range Profile Sequences and Doppler Signatures

open access: yesSensors, 2017
The frequency of terahertz radar ranges from 0.1 THz to 10 THz, which is higher than that of microwaves. Multi-modal signals, including high-resolution range profile (HRRP) and Doppler signatures, can be acquired by the terahertz radar system.

Eigenvalue‐based ground target detection in high‐resolution range profiles [PDF]

open access: yesIET Radar, Sonar & Navigation, 2020
In this study, the authors address the problem of range‐distributed target detection in sequential high resolution range profiles (HRRPs). They propose a modified scaled largest eigenvalue detector for static target in homogenous ground clutter. A set of secondary data, which are free of target signal and have the same distribution as the clutter in ...

Target identification using bistatic high‐resolution range profiles

open access: yesIET Radar, Sonar & Navigation, 2017
A novel target identification scheme that utilises high‐resolution range profiles (HRRPs), which are obtained using bistatic (BS) radar (BS‐HRRPs) and four‐dimensional (4D) parameter sets (PSs), is described. These PSs uniquely determine the BS‐HRRPs. In the proposed scheme, a new feature to cope with the scale variances of the BS‐HRRPs is devised by ...
