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.

Effect of Frequency on Micro-Doppler Signatures of a Helicopter

2019 International Conference on Advances in Big Data, Computing and Data Communication Systems (icABCD), 2019
Helicopters usually fly at considerably lower speeds as compared with fixed wing aircraft and the distinguishing features of helicopters are their main and tail rotors. The main rotors, constant altitude and speed can be used by radar, both to identify a target as a helicopter, and further can be used to get information about the helicopter type with ...

Micro-Doppler Signatures - Review, Challenges, and Perspectives

2014
The micro-Doppler signature is a distinctive characteristic of the observed micro-Doppler effect in an object. The “signature” is commonly used to refer to the characteristic expression of an object or a process. When examining the micro-Doppler effect, the distinctive micro-Doppler characteristic, i.e., the micro-Doppler signature of an object, allows

Micro-Range/Micro-Doppler Decomposition of Human Radar Signatures

IEEE Transactions on Aerospace and Electronic Systems, 2012
Recently, the use of micro-Doppler radar signatures for target classification has become an area of focus, in particular for the case of dynamic targets where many components are interacting over time. To fully exploit the signature information, individual scattering centers may be automatically extracted and associated over the full target observation.

Radar Micro-Doppler Signature of Wind Turbines

2014
The radar micro-Doppler signatures of wind turbines have been discussed in this chapter. Due to the extremely large dimension and blade rotation, an increasingly large number of wind turbines have become potential interference to radar operations. The interactions between wind turbines and radar especially weather radars are analyzed, and some examples
