| 摘要: |
| 针对传统MUSIC (multiple signal classification) 算法在锥面共形阵列极化-DOA (direction of arrival) 参数联合估计过程中计算复杂度较高的问题，利用单极化阵元构造极化敏感锥面共形阵列，并建立阵列接收信号模型.通过构造同极化接收子阵，将导向矢量中空域信息和极化域信息去“耦合”，在考虑阵元遮挡效应的条件下，结合秩损原理实现了基于降维MUSIC算法的极化-DOA多参数估计，减小了极化-DOA参数估计的计算量.通过计算机仿真证明了方法的有效性.

| Abstract: |
| Focusing on the problem of high computation complexity of MUSIC algorithm which is used for joint polarization-DOA estimation of conical conformal array, the signal model of conical conformal array is established and is built by single polarizative elements. Through the building of same polarizative sub-array, the polarization and DOA information of steering vector is de-coupled, considering the shadow effectors of conformal array, dimension reduced MUSIC is derived by rank reduction theory, which realizes polarization-DOA estimation by less computation complexity. The method has been verified by computer simulations.
