Performance Analysis of Oblique Projection Filtering Based on Polarization Sensitive Array
摘要
Abstract
The output Signal-to-Interference-and-Noise Ratio (SINR) of oblique projection and orthogonal projection filtering based on a polarization sensitive array is investigated. The output SINR formulae of the oblique projection and orthogonal projection filtering under both the ideal and array error conditions are derived. Under ideal conditions, the output SINR is a function of the spatial and polarized matching coefficient between the signal and interference whereas, under the array error condition, it is a function of the Interference-to-Noise Ratio (INR) and the perturbation momentum. The oblique projection filtering obtains the same output SINR as the orthogonal projection filtering under both conditions, but the output SINR of the maximum SINR principle filtering is the best. Further analysis shows that the oblique projection distorts the spatial and polarized properties of noise filtering while maintaining the amplitude and phase properties of the output signal, which are distorted in orthogonal filtering. The simulation results attest the reasonability of the analysis in this paper.关键词
