Three-dimensional (3-D) imaging plays a vital role in the recognition of spinning space
debris. However, the image may be blurred due to the range migration caused by fast …

This article presents a radar cross-section (RCS)-based statistical recognition system for
identifying/classifying unmanned aerial vehicles (UAVs) at microwave frequencies. First, the …

With regard to the multifunction radar transmitting sparse stepped-frequency-modulation
(SSFM) signal for inverse synthetic aperture radar (ISAR) imaging, the received echo signal …

Under high sea state, ship targets make complex maneuvering motions due to strong
disturbances such as sea waves and sea winds. Selecting the optimal imaging time interval …

Inverse synthetic aperture radar (ISAR) imaging can be improved by processing Range-
Instantaneous Doppler (RID) images, according to a method proposed in this paper that …

In the actual scene of interferometric inverse synthetic aperture radar (InISAR) imaging, the
noncooperative targets may make a nonuniform 3-D rotational motion (3-D-RM), which …

For targets with complex motion, the echo of inverse synthetic aperture radar (ISAR) is a time-
varying frequency signal in azimuth. Hence, the traditional range-Doppler (RD) algorithm …

For the target with 3-D rotation, the 3-D synthetic aperture radar (SAR) imaging is very
important for the feature extraction and classification. To solve this issue, a novel 3-D …

In this paper, we propose a fast and robust parameter estimate method for multi-component
linear frequency modulated (LFM) signals from a finite number of noisy discrete time …

Inverse synthetic aperture sonar (ISAS) can obtain the image of a moving underwater
vehicle (UV) with both high range resolution and high cross-range resolution. Existing ISAS …
