FDI A novel approach to wind profiling is presented which is based on the hybrid use of spatial and frequency domain interferometry.
Many algorithms exist that can be used to determine the wind field using spaced receiving arrays .
The cause of Doppler sorting is the Fourier transform used in the analysis of multi-receiver data. All pulsed radar systems are limited in range resolution by the length of the transmitted pulse. Therefore, wind estimates can be obtained for a discrete set of altitudes, determined by the gating of the received signal. Thus, the combined use of FDI and IDI can provide the radial and angular location of particular scattering points. FDI was then used to enhance the height resolution, producing a zoomed version of the SNR contour plot.
