Human Micro-Doppler Frequency Estimation Approach for Doppler Radar

IEEE Access, 2018
Micro-Doppler frequency estimation is an important issue for radar target recognition. In this paper, a novel approach is proposed to accurately estimate the micro-Doppler frequencies of specific target scattering parts, which can be very promising in ...

Modern spectral analysis in HF radar remote sensing. [PDF]

, 1998
High-Frequency (HF) radar systems are currently used to collect wave data. By applying spectral analysis methods, such as the Fast Fourier Transform (FFT) method, to the radar backscatter from the ocean surface, the so-called Doppler spectrum is ...
