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 …

合成孔径雷达(SAR) 能够全天时全天候获取感兴趣区域的高分辨率雷达图像,
在诸多领域获得了成功应用. 在电子对抗博弈环境下, SAR 图像解译与情报生成也面临复杂电磁 …

A novel feature extraction method based on micro-Doppler signature is proposed to
categorize ground moving targets into three kinds, ie, single walking person, two people …

The alternative use of the Global Navigation Satellite System (GNSS) has recently initiated a
number of studies that aim to exploit this system as an illuminator of opportunity for a passive …

For a target with rotating parts, the ISAR image of its main body may be overshadowed by
micro-Doppler signals, which are traditionally treated as interference and removed from …

The intricate vibration of a working vehicle provides an important signature to the vehicle
type. Small vibrations introduce phase modulation in radar echoes, which is referred to as …

A novel method is proposed for moving wheeled vehicle and tracked vehicle classification
using micro-Doppler features from returned radar signals within short dwell time. In this …

Ship targets are high-value military and civilian targets with broad application prospects.
However, the precise focusing of ships is still a difficult issue because of their complicated …

In this paper, an estimation method of micromotion parameters for free rigid targets using
micro-Doppler (mD) features is investigated. These parameters include spin rate, precession …

A vibration estimation method for synthetic aperture radar (SAR) is presented based on a
novel application of the discrete fractional Fourier transform (DFRFT). Small vibrations of …
