Surat ini menangani masalah pemprosesan penyesuaian ruang masa (STAP) untuk radar tatasusunan linear tidak seragam (NLA) bawaan udara menggunakan pembatal sidelobe umum (GSC). Disebabkan kesukaran menentukan nol spatial untuk NLA, adalah menjadi masalah untuk mendapatkan matriks penyekat (BM) GSC yang sah secara langsung. Untuk menyelesaikan masalah ini dan meningkatkan prestasi STAP, kaedah pengubahsuaian BM berdasarkan algoritma ortogonalisasi Gram-Schmidt yang diubah suai dicadangkan. Pemproses GSC yang diubah suai boleh mencapai prestasi STAP yang optimum dan serta kadar penumpuan yang lebih pantas daripada kaedah unjuran subruang ortogon. Simulasi berangka mengesahkan keberkesanan kaedah yang dicadangkan.

Abstract: This letter addresses the problem of space-time adaptive processing (STAP) for airborne nonuniform linear array (NLA) radar using a generalized sidelobe canceller (GSC). Due to the difficulty of determining the spatial nulls for the NLAs, it is a problem to obtain a valid blocking matrix (BM) of the GSC directly. In order to solve this problem and improve the STAP performance, a BM modification method based on the modified Gram-Schmidt orthogonalization algorithm is proposed. The modified GSC processor can achieve the optimal STAP performance and as well a faster convergence rate than the orthogonal subspace projection method. Numerical simulations validate the effectiveness of the proposed methods.
