Terahertz inverse synthetic aperture radar (ISAR) imaging with a quantum cascade laser transmitter
Optics Express, 2010 A coherent transceiver using a THz quantum cascade (TQCL) laser as the transmitter and an optically pumped molecular laser as the local oscillator has been used, with a pair of Schottky diode mixers in the receiver and reference channels, to acquire high-resolution images of fully illuminated targets, including scale models and concealed objects.

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 ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.To address the issues in radar automatic target recognition (RATR) based on high‐resolution range profiles (HRRP)—specifically, the inability of closed‐set methods to handle unknown categories and the limitation of conventional open‐set methods that can only reject unknown categories without further subdivision—this paper proposes the MHA–CoST open‐set

Subinteger Range-Bin Alignment Method for ISAR Imaging of Noncooperative Targets
EURASIP Journal on Advances in Signal Processing, 2010 Inverse Synthetic Aperture Radar (ISAR) is a coherent radar technique capable of generating images of noncooperative targets. ISAR may have better performance in adverse meteorological conditions than traditional imaging sensors.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.In this paper, we first establish the dual‐band airborne radar wideband echo signal model and propose a space‐time‐frequency adaptive processing method based on it. Firstly, in the passive mode, the poles of the dual band are estimated by the matrix pencil method, and the incoherent components are estimated through the phase relationship between the ...
