Because the signals of the target reflections are coherent , the reconstructing matrix algorithm which uses the time - shift correlation method is studied . not only has it the good ability to solve the coherence problem , but it also reduces the computation because of the time - shift correlation instead of the eigenvalue decomposition 由于雷達系統(tǒng)中目標回波具有相關(guān)性,必須考慮解相干處理,所以研究了利用時移相關(guān)去噪的矩陣重構(gòu)算法,該算法具有較好的解相干能力,且用時移相關(guān)去噪免去了特征分解去噪過程,可直接使用esprit算法求解旋轉(zhuǎn)不變關(guān)系,簡化了過程,減小了計算量。
