Space-time polarization anti-interference method based on alternate polarization sensitive array

Abstract

The invention provides a space-time polarization anti-interference method based on an alternate polarization sensitive array, and the method employs the alternate polarization sensitive array as a receiving model, and the array reduces the calculation burden and mutual coupling effect of the method. On the basis of a multilinear constraint criterion and space-time adaptive processing, polarizationinformation of signals is added according to polarization characteristics of satellite signals and interference signals. Compared with the traditional method, the method has the advantages that the influence of the cross-coupling effect of the polarization sensitive array with the orthogonal double dipoles is effectively reduced, and the anti-interference performance is not influenced; the problem that satellite communication and positioning are affected due to the fact that satellite signals are attenuated when expected satellite signals and interference signals are close in incoming wave direction or small in interval is effectively solved. The problem that the anti-interference capability fails when the two-dimensional domain information is similar is effectively solved; two-dimensional domain information is expanded to three-dimensional domain information, joint anti-interference of a space-time polarization three-dimensional domain is achieved, and a theoretical basis is providedfor anti-interference of a satellite receiver.

AI Technical Summary

Benefits of technology

This patented technology helps reduce errors caused when transmitting data through wireless communication channels without affects its quality or functionality. Its technical results include improved antimicrobial protection against jamming attacks, reduced processing power consumption for faster analysis times, enhanced spatial resolution capabilities (spatial filtering), increased immunity towards noise sources such as radioactive materials, better detection accuracy during radar systems, more efficient computation on multiple dimensions, etc., which are important applications in advanced military defense technologies like autonomous drones.

Problems solved by technology

This patents discuss how electronic devices like navigational satellites use radio signals transmitted through air interfaces such as sea water. These environments pose challenges towards maintaining accurate location tracking capabilities without being affected negatively. To address this issue, many new techniques called polarization inspections were explored during development stages but they still lack sufficient accuracy against external sources like strong solar radiation. There was no solution provided yet beforehand.
