This review explores radar‐based techniques currently utilised in the literature to monitor
small unmanned aerial vehicle (UAV) or drones; several challenges have arisen due to their …

Micro‐Doppler signals refer to Doppler scattering returns produced by the motions of the
target other than gross translation. The small micro‐motions of a subject, and even just parts …

In some applications, it is necessary to analyze multi-component non-stationary signals
whose components severely overlap in the time-frequency (TF) domain. Separating those …

In order to effectively detect moving targets in heavy sea clutter, the micro-Doppler (mD)
effect is studied and an effective algorithm based on short-time fractional Fourier transform …

In this letter, we propose an empirical-mode decomposition (EMD)-based method for
automatic multicategory mini-unmanned aerial vehicle (UAV) classification. The radar echo …

摘要雷达探测环境复杂, 探测对象特征多样, 回波具有低可观测性, 雷达探测性能难以满足实际
需求, 面临着复杂环境下微弱目标检测难题. 本文论述了低可观测动目标的内涵, 特征 …

Robust and effective detection of a marine target is a challenging task due to the complex
sea environment and target's motion. A long-time coherent integration technique is one of …

The micro-Doppler (mD) effect induced by the rotating parts or vibrations of the target
provides a new approach for target recognition. To obtain high range resolution for the …

Accurate detection and tracking of birds and drones are of great significance in various low
altitude airspace surveillance scenarios. Radar is currently the most proper long range …

Radar can obtain high spatial resolution at large operating distances, and its operation is
largely independent from weather and lighting conditions. This makes it an important …
