A Comprehensive Study of Past, Present, and Future of Spectrum Sharing and Information Embedding Techniques in Joint Wireless Communication and Radar Systems

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
Wireless spectrum is a limited resource, and the rapid increase in demand for wireless communication‐based services is increasing day by day. Hence, maintaining a good quality of service, high data rate, and reliability is the need of the day. Thus, we need to apportion the available spectrum in an efficient manner.

Crosstalk in modern software defined radio for the implementation of frequency modulated continuous wave radar

IET Radar, Sonar &Navigation, Volume 15, Issue 12, Page 1607-1621, December 2021., 2021
Abstract This study investigates crosstalk and leakage in the Software Defined Radio implementation of Frequency Modulated Continuous Wave (FMCW) radar systems. Empirical measurements of leakage power were conducted during the implementation of FMCW radar using National Instruments Universal Software Radio Peripheral (USRP) boards.

Broadband suppression of phase-noise with cascaded phase-locked-loops for the generation of frequency ramps [PDF]

, 2003
The generation of analogue frequency ramps with non-fractional phase-locked-loops (PLL) is a cost effective way of linearising varactor controlled oscillators (VCO).

Radar‐based monitoring of glass fiber reinforced composites during fatigue testing

Structural Control and Health Monitoring, Volume 28, Issue 10, October 2021., 2021
Summary This work aims at radar sensors in the frequency band from 57 to 64 GHz that can be embedded in wind turbine blades during manufacturing, enabling non‐destructive quality inspection directly after production and structural health monitoring (SHM) during the complete service life of the blade.

Phenomenology of automotive radar interference

IET Radar, Sonar &Navigation, Volume 15, Issue 9, Page 1045-1060, September 2021., 2021
Abstract Mutual interference in automotive radar is expected to become a major issue owing to the rapid increase in the number of vehicles on the road equipped with radar. The phenomenology of interference in frequency modulated continuous wave radar is presented. Interference is empirically analysed at every signal processing stage in the victim radar

Intrinsic synchrosqueezing analysis on micro‐Doppler features for small unmanned aerial vehicles identification with dual‐channel radar

IET Microwaves, Antennas &Propagation, Volume 15, Issue 7, Page 797-806, 10 June 2021., 2021
Abstract The micro‐Doppler (m‐D) effect depends on the rotation of rotor blades in addition to the translation of the platform. Thus it is a characteristic for identifying small unmanned aerial vehicles (UAVs). However, compared with the Doppler signal induced by the translation of the platform, the m‐D signal is weak.
