Micro-Doppler Signature Extraction with Multibeam Radar

2019 International Radar Conference (RADAR), 2019
Orthogonal and quasi-orthogonal waveforms are used in a multibeam radar (MBR) to isolate different channels and reduce cross-channel interference. Each channel provides an independent radar beam that performs a specific functionality without interfering with adjacent channels.

Analytic radar micro-Doppler signatures classification

SPIE Proceedings, 2017
Due to its capability of capturing the kinematic properties of a target object, radar micro-Doppler signatures (m-DS) play an important role in radar target classification. This is particularly evident from the remarkable number of research papers published every year on m-DS for various applications.

Human Action Categorization Using Ultrasound Micro-Doppler Signatures

2011
The spectrotemporal representation of an ultrasonar wave reflected by an object contains frequency shifts corresponding to the velocity of the object's moving parts, also known as the micro-Doppler signature. The present study describes how the micro-Doppler signature of human subjects, collected in two experiments, can be used to categorize the action

Empirical mode decomposition of micro-doppler signature

IEEE International Radar Conference, 2005., 2005
Micro-Doppler induced by mechanical vibration or rotation of structures in a radar target is potentially useful for target detection, classification and recognition. In order to exploit the time-varying micro-Doppler signature, time frequency analysis techniques are used. However, they can not represent this useful information clearly all the time.

Target classification based on micro-doppler signatures

IEEE International Radar Conference, 2005., 2005
In this paper, we propose a Gabor filtering method to extract localized micro-Doppler signatures represented in the time-frequency domain. The dimensionality of the extracted Gabor features is further reduced by using the principal component analysis (PCA) method.

Phenomenology of Radar Micro-Doppler Signatures

2014
In this chapter, we introduce mathematics of the micro-Doppler effect in radar, derive basic formulas of micro-Doppler shifts due to vibration, rotation, tumbling and conning, and extract micro-Doppler signatures using time-frequency analysis.

Micro-Doppler signatures for sensing micro-motion

2019
The micro-Doppler signature is a distinctive characteristic of micro-motion represented by intricate time-varying Doppler frequency modulations. It can be used to extract motion kinematic features for identifying an object of interest. In this Chapter, we introduce the micro-Doppler signature in radar and its applications for sensing micro-motion.
