Phenomenology of Radar Micro-Doppler Signatures
2014In 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.

Effect of Frequency on Micro-Doppler Signatures of a Helicopter
2019 International Conference on Advances in Big Data, Computing and Data Communication Systems (icABCD), 2019Helicopters 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 ...

Sonar Micro-Doppler Signatures: Principles and Applications
2014In this chapter we introduce the theory behind sonar micro-Doppler signatures and highlight advantages and disadvantages with respect to their radar counterpart. We present the results of two experimental trials carried out at (1) the U.S. Army Research Laboratory and (2) University College London in which sonar micro-Doppler signatures of personnel ...

Micro-Doppler Signatures - Review, Challenges, and Perspectives
2014The 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

Radar Micro-Doppler Signature of Wind Turbines
2014The 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

Individual classification through autoregressive modelling of micro-doppler signatures
2012 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2012This paper introduces the use of autoregressive modelling (AR) to characterize individual human gait signatures from micro-Doppler data. AR models are fitted to micro-Doppler data obtained while 6 subjects walk towards a custom-made ultrasonic transceiver module. The estimated AR coefficients capture individual movement characteristics.

Micro-Doppler Signatures of Helicopter Rotor Blades
2014The work presented in this chapter has shown how to take advantage of the microDoppler features of the rotary parts of a helicopter. Traditionally, analysis of the amplitude variations of the target echo returns have been used in order to separate fixed wing and rotary wing aircraft.
