Adaptive Interference Removal for Un-coordinated Radar/Communication Co-existence

open access: yes, 2017
Most existing approaches to co-existing communication/radar systems assume that the radar and communication systems are coordinated, i.e., they share information, such as relative position, transmitted waveforms and channel state.

Backscatter Transponder Based on Frequency Selective Surface for FMCW Radar Applications [PDF]

open access: yes, 2014
This paper describes an actively-controlled frequency selective surface (FSS) to implement a backscatter transponder. The FSS is composed by dipoles loaded with switching PIN diodes. The transponder exploits the change in the radar cross section (RCS) of

Coexistence of 5G Communication Systems With Radar Altimeters

open access: yesIEEE Access
With the growing demand for 5G, many countries have allocated additional spectrum above 3.7 GHz, potentially causing serious interference to radar altimeters operating at the 4.2–4.4 GHz band. Therefore, in this paper, a general mathematical model

Hybrid interference suppression for multistatic radar

open access: yesIET Radar, Sonar & Navigation, 2008
The accurate estimation of a monostatic radar range profile is considered when in the presence of multistatic radar interference for which the illuminating waveforms are assumed known. In an effort to approach the ideal interference-free performance, the range-domain 'beamforming' properties of the recently developed multistatic adaptive pulse ...
