Sentence examples for That isar from inspiring English sources

The SNR problem is among the most significant challenges that ISAR imaging systems frequently face.

It has been proposed in [12] that ISAR image can be reconstructed using much fewer pulses than RD algorithm with random pulse repetition interval (PRI).

The authors concluded that ISAR is a useful screening tool for frailty and identifies those at risk of adverse outcomes after an acute emergency department visit.

Motion compensation and imaging are among the most significant challenges that SA-ISAR imaging frequently faces.

It is notable in Table 1 that a well focused ISAR image was obtained by using the improved PFA.

Unless an optimal translational motion compensation is obtained, serious blurring can result in the ISAR image formed by the inversed Fourier transform, which assumes that the scatter behaves with only the linear phase exp − j 4 π x ω eff t λ.

As mentioned before, the ISAR image represents the local spatial structure and energy-assembling characteristic of the target scattering field, which means that neighboring components tend to be large or small simultaneously.

As a proof of that, Figures 16(a) and 16(b), respectively, show the range profiles and the ISAR image for the noncooperative data of Figure 14 after applying this global range alignment approach.

It should be emphasized that, in the wide-angle ISAR imaging, the Keystone usually cannot correct the distinctive high-order MRTCs, but it still plays a significant role for a better estimation of the chirp rate with ICPF.

Thus, we believe that the estimates of the ISAR to predict such adverse outcomes are broadly correct.

A bridge was built across the Isar the following year, and the marketplace was fortified.
