The reported location is the centroid of the location of each contributing target. This merging of multiple targets into a single detection is common at long ranges, because the area covered by the radar's azimuth resolution grows with increasing distance from the sensor. Create a scenario with ...
.,M−1. The axes origin is chosen in the array centroid, i.e., Eq. (68) holds. Assume an unit amplitude harmonic wave of frequency ω emanates from a generic PWAS source located at the origin O. The wave front propagates radially with wavespeed c. The wave front at a point P(...
For each echo ambiguous return, the equivalent depth is estimated by considering the difference between the vertical value of its coordinates centroid and the estimated position of the surface echo (Supplementary Fig. 3). We limited the analysis to the first 1000 m of subsurface depth according...
Then the data is stored and plots centroid processing is performed. If the ADS-B data is existed in the inquiry channel and the control channel, selection is performed during the plots centroid processing according to amplitude information and the confidence information. The above processing can be...
Since the analysis in the previous section focused on finding the centroid of the brightest first-hop signal on the sky, these sidelobes were of little concern. However, as we attempt to map the HF reflectance using the detected power from several different directions at once, confusion from ...
Trade-offs between model parameters, also estimated by this technique, are also small; the most important (i.e., the trade-offs between fault slip, fault width, centroid depth, and moment) involve only around 10% variations in the involved parameters. Table 3. Source Parameters of the Bam ...
The centroid is found by integrating the spectrum over the first-order energy band. The frequency corresponding to the centroid of the spectrum is taken as the frequency of the Bragg line. The surface-current-induced displacement (Δf) in the Doppler shift (see Figure 4.3) is determined by ...
than in the broadside case, and experienced lower attenuation than the attenuation at the centroid. As such, the target signal at that range is visible in the filtered data. The second target at a greater range is not visible because the clutter return at that range was not attenuated as ...
By implementing this technique, the reflections of the moving target in the MF-RDMs can be focused on the Doppler centroid (DC) of the target, ultimately achieving the correction of the MF-DFM. 2. To remove the residual phase errors following the MF-RFT, a phase-compensation-based method ...
Furthermore, different distances from the centroid of the objects to the outlet of the catchment were obtained. Illustrating this with the example from Figure 7, the smaller object is positioned closer to the outlet, resulting in a shorter distance. This information is relevant for the model as...
