The parameters of the ground clutter signal are the same as in Fig. 3, but for a composite signal typical of a ground clutter and weather mix. 3, but the mean Doppler velocity is 0 m s −1 and the spectrum width is 8 m s −1.Īs in Fig. 3, but the mean Doppler velocity is 20 m s −1 and the spectrum width is 0.28 m s −1.Īs in Fig. 3, but for a simulated staggered-PRT sequence typical of ground clutter returns the mean Doppler velocity is 0 m s −1 and the spectrum width is 0.28 m s −1.Īs in Fig. The dotted lines in the phase plots correspond to the aliased theoretical ASD phases of the underlying uniform-PRT sequence, and the solid lines correspond to the measured ASD phases of the corresponding staggered-PRT sequence.Īs in Fig. The sequence has 65 samples with T 1 = 1 ms and T 2 = 1.5 ms, the SNR is 40 dB, the mean Doppler velocity is 0 m s −1, and the spectrum width is 2 m s −1. (top) Magnitude and (bottom) phase of the ASD at lags (left) 2/5, (center) 3/5, and (right) 1 as a function of Doppler velocity for a simulated staggered-PRT sequence typical of weather returns. Light lines labeled with roman numerals in the bottom plot correspond to the aliased ASD phases from the same subinterval in the ASD of the underlying uniform-PRT sequence. Dotted vertical lines partition the Nyquist cointerval corresponding to the underlying uniform-PRT sampling into five subintervals (I–V) that alias and combine to form the ASD of the staggered-PRT sequence. (bottom two) Example of the lag-2/5 ASD for a staggered-PRT sequence with a PRT ratio of 2/3 and (top two) the corresponding lag-2 ASD for the underlying uniform-PRT sequence. The remaining panels illustrate the first three uniform-PRT subsequences with sampling period T s that can be obtained from the staggered-PRT sequence. (top) Staggered-PRT sampling (solid lines) via decimation of an underlying uniform-PRT sequence with sampling period T u (dotted lines).

This view provides a full map view of all alert hazards (similar to WWA map). This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. This view combines radar station products into a single layer called a mosaic and storm based alerts. This view provides specific radar products for a selected radar station and storm based alerts. This site is organized into views that provide relevant radar products and weather information for a common task or goal.
