Partial polarization signal multi-parameter estimation method based on non-co-located non-uniform polarization array
A polarized signal and non-uniform technology, which is applied in direction finders using radio waves, radio wave direction/deviation determination systems, etc., can solve problems such as ambiguity of incoming wave direction, reduction of array aperture, and increase of mutual coupling. To achieve the effect of saving resources

[0098] Simulation Example 2: Verify that the method of the present invention with the estimation accuracy of the polarization degree with the signal to noise ratio, the number of snapshot is fixed in 200, the signal-to-noise ratio is set to -10 dB to 20dB, and other simulation conditions are the same as the last experiment. . From Image 6 We can see that the root mean square error of the polarization decreases as the signal-to-noise ratio is increased, with higher estimation accuracy. The following table shows the method of the method of the present invention in the signal to noise ratio of 10 dB, and the remaining simulation conditions are the same as the above experiment, and the estimated table of polarization parameters is as follows:
