| 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. |
