Abstract EN
Due to the polarization mismatch of the antenna, the received signal suffers from energy loss.
The conventional beamforming algorithms could not be applied to the conformal array because of the varying curvature.
In order to overcome the energy loss of the received signal, a novel joint polarization-space matched filtering algorithm for cylindrical conformal array is proposed.
First, the snapshot data model of the conformal polarization sensitive array is analyzed.
Second, the analytical expression of polarization sensitive array beamforming is derived.
Linearly constrained minimum variance (LCMV) beamforming technique is facilitated for the cylindrical conformal array.
Third, the idea of joint polarization-space matched filtering is presented, and the principle of joint polarization-space matched filtering is discussed in detail.
Theoretical analysis and computer simulation results verify that the conformal polarization sensitive array is more robust than the ordinary conformal array.
The proposed algorithm can improve the performance when signal and interference are too close.
It can enhance the signal-to-noise ratio (SNR) by adjusting the polarization of the elements of the conformal array, which matches the polarization of the incident signal.
