Proposal of multiple access FMCW radar for inter-radar interference avoidance

open access: yesThe Journal of Engineering, 2019
Inter-radar interference will be a crucial problem when a number of frequency modulated continuous wave (FMCW) radars are densely deployed in future, since it can cause miss detection and false detection of the target due to wideband interference and ...

Space scanning FMCW-based two-dimensional frequency diverse array radar

open access: yesThe Journal of Engineering, 2019
The frequency-modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is extended to two dimensions (2D). The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased ...

Dechirp‐receiving radar target detection based on generalized Radon‐Fourier transform

open access: yesIET Radar, Sonar & Navigation, 2021
The dechirp‐receiving radar measures range by the frequency difference between the target echo and the reference signal. It can operate at a low sampling frequency while transmitting a wideband signal, which simplifies the radar hardware.

UAV target detection and parameter estimation in non-homogeneous clutter

open access: yesThe Journal of Engineering, 2019
Aiming at the problem of UAV target detection and parameter estimation in non-homogeneous clutter with STLFMCW radar, a SK-CFAR detector is proposed based on the local spectrum refinement.

FM/CW radar system [PDF]

open access: yes, 1978
An FM/CW radar system is presented with improved noise discrimination in which the received signal is multiplied by a sample of the transmitted signal, and the product signal is employed to deflect a laser beam as a function of frequency. The position of

Ambiguity function and accuracy of the hyperbolic chirp: comparison with the linear chirp [PDF]

open access: yes, 2017
In this paper, we derive the Ambiguity Function (AF) of a narrowband and a wideband hyperbolic chirp. We calculate the second derivatives of the squared amplitude of the narrowband Complex Ambiguity Function (CAF) and use them to calculate the Fisher ...

XOR‐Logic Phase Coding Programmable Metasurface for Low Power‐Consumption Systems

open access: yesAdvanced Science, EarlyView.
By leveraging XOR logic, the biasing‐network complexity of 2D programmable metasurfaces is reduced from m×n to m+n through efficient row‐column control. This enables versatile functions including beam deflection and beamforming, facilitating applications in wireless communications and beyond.
