Kertas kerja ini membentangkan kaedah reka bentuk penapis spatial berwajaran (WSF) berdasarkan anggaran arah ketibaan (DOA) untuk konfigurasi tatasusunan baru yang dipanggil tatasusunan gabungan jumlah dan perbezaan. Tatasusunan gabungan jumlah dan perbezaan pada asasnya adalah gabungan tatasusunan jumlah dan perbezaan. Konfigurasi kami boleh merealisasikan darjah kebebasan (DOF) yang lebih tinggi dengan jumlah bahagian tatasusunan bersama pada kos pengiraan yang lebih rendah daripada tatasusunan jarang yang lain. Untuk meningkatkan lagi keteguhan susunan bersama komposit jumlah dan perbezaan yang dicadangkan, kami mereka bentuk corak rasuk optimum oleh WSF berdasarkan maklumat anggaran DOA. Prestasi sistem yang dicadangkan dan ketepatan anggaran DOA bagi gelombang yang menghampiri dinilai melalui simulasi komputer.

Abstract: This paper presents a weighted spatial filter (WSF) design method based on direction of arrival (DOA) estimates for a novel array configuration called a sum and difference composite co-array. A sum and difference composite co-array is basically a combination of sum and difference co-arrays. Our configuration can realize higher degrees of freedom (DOF) with the sum co-array part at a calculation cost lower than those of the other sparse arrays. To further enhance the robustness of our proposed sum and difference composite co-array we design an optimal beam pattern by WSF based on the information of estimated DOAs. Performance of the proposed system and the DOA estimation accuracy of close-impinging waves are evaluated through computer simulations.
