Distributed MIMO-ISAR Sub-image Fusion Method
Leida xuebao, 2017 The fast fluctuation associated with maneuvering a target’s radar cross-section often affects the imaging performance stability of traditional monostatic Inverse Synthetic Aperture Radar (ISAR).

CLEAN Technique for Polarimetric ISAR [PDF]
International Journal of Navigation and Observation, 2008 Inverse synthetic aperture radar (ISAR) images are often used for classifying and recognising targets. To reduce the amount of data processed by the classifier, scattering centres are extracted from the ISAR image and used for classifying and recognising targets.

Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis
Hepatology, EarlyView., 2022 Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.

Developments in target micro-doppler signatures analysis: radar imaging, ultrasound and through-the-wall radar [PDF]
, 2013 Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Passive ISAR for harbor protection and surveillance
, 2018 This chapter presents the application of the PB-ISAR (passive bistatic-ISAR) technique to data collected in a harbor area. The results show the effectiveness of PB-ISAR algorithm for the purposes of harbor protection and surveillance.

Polarimetric ISAR autofocusing
IET Signal Processing, 2008 Interest in polarimetric inverse synthetic aperture radar (ISAR) systems has been growing because of their capability to provide extra information about the imaged target compared with single polarisation ISAR systems. Target classification and recognition can be improved by exploiting full polarisation ISAR images.

Axial Attitude Estimation of Spacecraft in Orbit Based on ISAR Image Sequence
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Attitude estimation is a significant task for monitoring noncooperative spacecraft in orbit. Inverse synthetic aperture radar (ISAR) is an effective method to obtain the structure, size, and attitude of spacecraft.

Analog Frequency Tracking Filter
Advances in Electrical and Computer Engineering, 2013 This paper propose a new type of analog adaptive filter derived as a generalization of the concept of matched filter. We conceive such a filter to track the instantaneous frequency of frequency modulated signals.
