Coherent Source Localization: Bicomplex Polarimetric Smoothing with Electromagnetic Vector-Sensors
Xiao‐Feng Gong, Zhiwen Liu, Yougen Xu · IEEE Transactions on Aerospace and Electronic Systems · 2011
The work presented here considers coherent source localization with bicomplex. A new polarimetric smoothing variant is proposed by using bicomplex modeled subarrays obtained from complete electromagnetic vector-sensor array, and a MUSIC-like algorithm is further developed. The identifiability, computational complexity, and the choice of selection vectors for the proposed method are also addressed. Simulations show that the proposed method can provide better direction-of-arrival estimates than the complex methods in perturbations caused by noise, short data, and model errors.
