Principles and Applications of Relax: A Robust and Universal Estimator
暫譯: Relax 原則與應用：一種穩健且通用的估計器

多重信號解混和參數估計問題是由背景噪聲和干擾影響所引起的，這些問題在雷達、聲納、通信和導航等領域中經常遇到。信號處理和控制領域的研究一直專注於提高低信噪比（SNR）下參數估計方法的估計性能，並在模型誤差存在的情況下保持估計的穩健性。本書提出了一種通用且穩健的放鬆估計方法（RELAX），並介紹其在經典線譜估計、延遲時間估計、到達角（DOA）估計和雷達目標成像等領域的基本原理和應用。這些信息被全面且詳細地解釋，並使用與浪漫關係相關的隱喻來形象化參數估計的基本問題、五種經典參數估計方法的基本原理以及這些原理之間的關係。本書作為信號處理和控制領域科學家和技術人員的參考資料，同時也為相關領域的研究生提供了相關信息。
