Broadband multi‐carrier linear frequency modulation signal reception with subcarrier frequency offset deramp processing

open access: yesIET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2325-2332, November 2024.
The authors propose a multi‐carrier LFM signal reception method based on subcarrier frequency offset deramp processing. By properly introducing a carrier frequency interval difference between the transmit and reference signals, multi‐carrier LFM signal deramp processing is implemented through frequency mixing, which allows crosstalk‐free separation of ...

Three dimensional scattering center imaging techniques [PDF]

open access: yes
Two methods to image scattering centers in 3-D are presented. The first method uses 2-D images generated from Inverse Synthetic Aperture Radar (ISAR) measurements taken by two vertically offset antennas.
