Due to the lack of labeled radar complex data, we construct a radar echo dataset with multiple signal-to-noise ratio (SNR) for RTD. Then, the CNN-based model is evaluated on the dataset. The experimental results demonstrated that the CNN-based detector has better detection performance and ...

dataset. The cases with the echo area coverage greater than 1/10 in the effective detection range of the radar are selected into the sample data set, and the radar echo range is controlled within the range of 0–70 DBZ. Figure7shows the visualized images of a group of samples in the da...
The dataset includes 894,916 timesteps of precipitation from more than 9 years of data, offering a novel resource to develop and benchmark analog ensemble models and machine learning solutions for precipitation nowcasting. Data are ... G Franch,V Maggio,L Coviello,... - 《Scientific Data》 被...
We used radar reflectivity factor, a measure observed bird density on the ground, 2) the spatial heterogeneity of returned radar echo strength based on the dielectric properties and extent of spatial autocorrelation of radar measures, and 3) the of water in units of Z (mm6 m23) and ...
The self-established dataset contains the radar echo data of 5 human activities. They are walking, running, standing up after squatting down, bending, and turning respectively. The self-established dataset collects the human activities of 10 participants, including 7 males and 3 females. To ...
The dataset containing 27920 1-min DSD measurements was used in our estimation. computed from disdrometer data. It is clear that the difference between ZDR(S) and ZDR(C) becomes significant for ZDR(S) > 2 dB, i.e., for DSD dominated by large drops. For such DSDs, the difference in ...
Therefore, in this study, we constructed the Fusion GRU module, which leverages a cascade structure to effectively combine radar echo data and mean wind data. We also designed the Top Connection so that the model can capture the global spatial relationship to construct constraints on the ...
Typically, an operator would define a fixed time window length (CPI) and would process the entire dataset by sliding the window and forming ISAR images. The same Image scaling Inverse Synthetic Aperture Radar generates two dimensional, high resolution images of targets in the time delay—Doppler ...
Once the spectrum is calculated, the derivation of atmospheric parameters is in principle simple. Given a bell-shaped spectral feature occupying, say, a fifth of the measured spectrum, its integral (zeroth moment) gives the echo power, its first moment theradial velocityand its second moment the...
