A Flexible K‐Band FMCW Radar Prototype for Low‐RCS Nano‐Drone Detection

open access: yesIET Radar, Sonar & Navigation
Nano‐drones are insect‐like drones used to provide intelligence through their capability of intrusion and ability to carry small sensors. They pose a defence and security threat and can potentially violate secure establishments and privacy rights.

Investigation on reason of range profile distortion of plasma sheath target

open access: yesThe Journal of Engineering, 2019
The range profile of the plasma sheath target is always found to be distorted when using the linear frequency modulation signal as the radar detection signal. As a result, the detection and tracking of the target became hard, or even failure. Here, three

Micro-motion feature extraction of space targets based on sinusoidal frequency modulation Fourier transform

open access: yesThe Journal of Engineering, 2019
The space target can be discriminated from other objects by the micro-motion feature difference. The micro-motion features of a space target with precession include the spinning period, the precession angle and the precession period etc. The main work of

Ground clutter simulation for airborne forward-looking multi-channel LFMCW radar

open access: yesThe Journal of Engineering, 2019
Ground clutter is a crucial factor that affects the detection performance of the airborne forward-looking multi-channel linear frequency modulated continuous wave (LFMCW) radar, so the distribution characteristics of studying the ground clutter plays an ...

Newtonalized orthogonal matching pursuit for the linear frequency‐modulated pulse frequency agile radar

open access: yesIET Radar, Sonar & Navigation, 2021
The linear frequency‐modulated frequency agile radar (FAR) can be used for synthesizing high‐range‐resolution profiles (HRRP), and also has excellent electronic counter‐countermeasures performance. Similar to the Newtonalized orthogonal matching pursuit (
