WebOct 1, 2024 · The current paper takes the advantage of the multi-component measurements of vector-sensors combined with the elegant nested array strategy to design a new coarray processing technique. In this way, we utilize the auto/cross-correlation matrices of the underlying subarrays of the nested EMVS array to serve as snapshots in the coarray … WebAn example is shown in Figure 3a, where two identical linear nested arrays with N 1 = 12, N 2 = 5 are utilized. The difference coarray of this cross-product nested array is a uniform rectangular array with aperture b N × d M. Note that this method requires a total of M N antennas and exhibits a high redundancy ratio. As such, a less-redundant ...
WebDec 11, 2024 · The Coarray "Hello World" sample is a terrible sample, as it doesn't use coarrays at all.
