Resolution and Micro-Doppler Effect in Bi-ISAR System (in English)

Leida xuebao, 2013
Compared to the monostatic radar, bistatic radar has many special characteristics because of its spatial complexity. Bistatic Inverse Synthetic Aperture Radar (Bi-ISAR) can be employed as a radar imaging tool for obtaining non-cooperative target images ...

Target detection, ISAR imaging and tracking capabilities of a passive radar net utilising barrage jamming signals

IET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2144-2154, November 2024.
This paper demonstrates the possibility of utilising a ground‐based barrage jammer as an illumination source for passive radar detection, tracking and ISAR imaging. This article will present some of the outcomes of field trials conducted within the international electronic warfare exercises.

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

IET 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 ...
