Abstract:

A polarization sensitive conical conformal array antenna with crossed dipole elements was formed and its uniform data model was built, based on which, by employing the special structure properties of single curvature surface,  the sub-arrays was found to agree with the rotational invariance relationship required by the ESPRIT algorithm and  a joint estimation method of 2D DOA and polarization was proposed. Monte-Carlo simulation results show that the proposed algorithm is competent to solve the problem of joint 2D DOA and polarization estimation based on conical conformal array antenna (CAA).
 

Key words: conformal array antenna, polarization diversity, estimation of signal parameters via rotational invariance technique(ESPRIT), polarization estimation
