As explained in Section 8.4.2.3, the use of a true-motion radar presentation for parallel indexing requires an ability to ground-stabilize the display reliably. Assuming that this condition can be met, the PPI may be used as an extension of the chart. The navigational data additional to the...
This can be explained by the fact that the ratio 𝑓D/Δ𝑓fD/Δf corresponds to a shift in samples in the discrete-frequency domain. Therefore, the same shift by 𝑓D/Δ𝑓fD/Δf samples becomes relatively less relevant in comparison to the total number of samples 𝑁PRBSNPRBS as ...
The sea surface normalized radar backscatter cross-section (NRCS) and Doppler velocity (DV) exhibit energy at low frequencies (LF) below the surface wave peak. These NRCS and DV variations are coherent and thus may produce a bias in the DV averaged over
However, in order to match these Ze to the observed S(v), the reported Ze were adjusted downward, as explained further in Appendix A.2, because the attenuation is likely greater than that used in the MRR calculations, which were based upon the usually erroneous assumption that the vertical ...
Then, temporal variations due to mobility in the channel can be simply represented using a linear fading process on each tap arrival. However, as explained in [6], in wideband communication systems, mobility must be characterized by time/frequency scaling. In addition, in a multipath environment...

(35) As explained before, and as one can observe, the equation of the information filters remains the analog of the ones presented and proposed for previous derivations of unscented information filters, cubature information filters, and Gauss–Hermite information filter; the main difference (as ...
Both patterns can be explained, although partially, by looking at the wind data of the WRF-ARW model wind: the arrows' direction (Figure 6D) indicates in fact the presence of a wind blowing towards the sensor (upwind condition). However, the north pattern has a sharper transition than the...
Thus, we cannot simply decouple the azimuth and elevation two-dimensional problem into two one-dimensional problems like planar antenna. Here we also used numerical calculation to observe the effect of steering vector mismatching, as shown in Figure 6. Figure 5. Schematic diagram of the mismatch ...
