A film-shaped aperture array includes a first principal surface and a second principal surface opposed to each other and a plurality of apertures penetrating the first principal surface and the second principal surface. A projection projecting from the second principal surface in a normal direction ...
300 km) with classical array processing techniques. Under the assumption that the incoming wavefronts are planar and originate from distances much larger than the array aperture, coherent signals across the array are stacked to enhance the signal-to-noise ratio, whereas the time delays between...
The categorization to one of the two cases depends on the aperture of the array and the distance between the source and receiver. As illustrated in Fig. 1, the wavefront originating from a source in the far-field can be described as a plane wave. The angle of incidence is identical for...
In practice, one needs to choose the appropriate synthesis method according to the specific constraint of the application, such as the size of the array aperture, the shape of the array geometry, etc. Reference [1] Randy L. Haupt, Thinned Arrays Using Genetic Algorithms, IEEE Transactions on ...
