Konfigurasi pelapik tiga peringkat menyediakan apertur maya berterusan yang lebih besar dan mencapai lebih banyak darjah kebebasan (DOF) untuk anggaran arah ketibaan (DOA) dibentangkan. Penambahbaikan itu direalisasikan dengan melantunkan tiga peringkat jarak antara elemen yang sama dengan sewajarnya. Setiap peringkat secara berfaedah mempamerkan tatasusunan maya berterusan, yang kemudiannya menghasilkan tatasusunan linear seragam tanpa lubang yang terhasil. Pendekatan geometri kekal terpakai untuk mana-mana struktur tatasusunan jarang sedia ada dengan coarray tanpa lubang, serta direka pada masa hadapan. Selain membesarkan apertur maya berterusan dan DOF, reka bentuk yang dicadangkan menawarkan fleksibiliti supaya ia boleh direalisasikan untuk sebarang bilangan antena. Selain itu, konfigurasi padding khas ditunjukkan, yang meningkatkan lagi bilangan penderia maya berterusan. Lokasi antena yang tepat dan bilangan kedudukan maya berterusan mendapat manfaat daripada ekspresi bentuk tertutup. Kerja-kerja eksperimen dijalankan untuk menunjukkan keberkesanan konfigurasi yang dicadangkan.

Abstract: A three-stage padding configuration providing a larger continuous virtual aperture and achieving more degrees-of-freedom (DOFs) for the direction-of-arrival (DOA) estimation is presented. The improvement is realized by appropriately cascading three-stages of an identical inter-element spacing. Each stage advantageously exhibits a continuous virtual array, which subsequently produces a hole-free resulting uniform linear array. The geometrical approach remains applicable for any existing sparse array structures with a hole-free coarray, as well as designed in the future. In addition to enlarging the continuous virtual aperture and DOFs, the proposed design offers flexibility so that it can be realized for any given number of antennas. Moreover, a special padding configuration is demonstrated, which further increases the number of continuous virtual sensors. The precise antenna locations and the number of continuous virtual positions are benefited from the closed-form expressions. Experimental works are carried out to demonstrate the effectiveness of the proposed configuration.
