For the polarimetric-Doppler weather radar, sometimes there are artifacts caused by radar system itself or external sources displaying in the radar plan position indicator (PPI). These artifacts are not confined to specific range bins and also they are non-stationary when observed in the Doppler domain. This paper puts forward a method to suppress such clutter by designing the generalized spectral...
This paper proposes a practical implementation for the generation of real-time K-Distributed correlated sea-clutter in firmware. The method uses a dual cumulative distribution function (CDF) based look-up method to transpose a complex uniformly distributed random variable (RV) to the required RV. The clutter is correlated by means of a filter process before translation, and it is shown that this technique...
2D Fresnel-Kirchhoff diffraction approach is applied to forward scattering of radar signals at a rotor of a wind turbine (WT). Quasi-static diffraction loss and phase shift as well as instantaneous Doppler shift of the two-way signal due to diffraction at more than one blade of a three blade rotor is investigated which is of particular importance if the rotor axis lies within the radar beam. Comprehensive...
In this paper the influence of clutter power spectrum on unambiguous radar target detection with single low pulse repetition frequency wideband waveform is analyzed. Impact of both stationary and diffuse clutter components for different signal bandwidths and coherent processing intervals (CPI) is studied. Exponential model of the ground clutter power spectrum for the diffuse component is used. For...
