摘要

迭代二次极大似然IQML和方向估计MODE方法是众所周知的“高分辨率”到达方向DOA估计方法。它们的解导致了一个带约束的优化问题。通常的线性约束对某些DOA值表现出较差的性能。本文提出了一种适用于两种DOA方法的新的线性约束，并将其性能与另外两种方法(单位范数和常规线性约束)进行了比较。结果表明，该方案优于其他约束条件。最后对计算复杂度进行了研究。

Constraints implementation for IQML and MODE direction-of-arrival estimators

The iterative quadratic maximum likelihood IQML and the method of direction estimation MODE are well known "high resolution" direction-of-arrival DOA estimation methods. Their solutions lead to an optimization problem with constraints. The usual linear constraint presents a poor performance for certain DOA values. This work proposes a new linear constraint applicable to both DOA methods and compares their performance with two others: unit norm and usual linear constraint. It is shown that the proposed alternative performs better than other constraints. The resulting computational complexity is also investigated.
