Development of space technology and the increase of space activities lead to the increasing of the space targets. For the safety of space, imaging and recognition of space target will be beneficial to reduce the danger of space activities. In this paper, we analyze the characteristic parameters of the spinning target based on distributed radar networks, and propose an algorithm to get these parameters...
Micro-Doppler (m-D) effect is regarded as a unique signature for the targets with micro-motion parts. It may contaminate the target's inverse synthetic aperture radar (ISAR) image and make the focused target hard to recognize. Meanwhile, multiple function radar system inevitably brings sparse apertures in practice due to its limited resources. In this paper, a method aiming at the ISAR imaging for...
This paper focuses on the identify capability of non-cooperative static ship in narrowband airborne radar. The three-dimensional micro-motion equations included yaw, pitch and row of static ship are built based on target's scatter point model firstly. Then effects to real-time distance between radar and ship's scatter point are analyzed. The echo of single frequency continuous wave radar is obtained...
Although the micro-Doppler (m-D) effect can provide additional information for target recognition, the microwave radar cannot afford enough resolution to detect the m-D effect of small targets and long distance targets. To obtain high range resolution for the extraction of the fine m-D signatures, inverse synthetic aperture imaging LADAR (ISAIL) is used here. Because of the frequency modulation continuous...
SIMO (Single Input Multiple Output) radar system capitalizes on the receiving diversity, so it can obtain more information about the target and highly improve the target recognition capability of radar. In this paper, the micro-Doppler effect induced by rotation and vibration parts of target in SIMO radar system which transmitting single frequency signal are deduced respectively. Both the micro-Doppler...
