摘要

在不改变阵列孔径的前提下,为增加导航抗干扰天线的自由度,提升系统抗干扰能力,提出了一种基于极化敏感阵列的空频域抗干扰方法。首先建立了极化敏感阵列信号模型;其次根据导航信号特点,采用功率倒置原理联合空频极化域求解自适应权值;最后以双正交极化天线为例,验证了该方法的有效性。仿真结果表明,由于利用了信号极化域信息,文中方法能够抑制大于阵元数的干扰源,并保持期望信号的增益。

Abstract

Without changing the aperture of the array, in order to increase the freedom of navigation anti-jamming antenna and improve the anti-jamming capability of the system, a space-frequency domain anti-jamming method based on polarization sensitive array is proposed. Firstly, the polarization sensitive array signal model is established. Secondly, according to the navigation signal characteristics, the adaptive weight in the space-frequency-polarization domain is obtained in the power inversion principle. Finally, effectiveness of this approach is validated by taking dual-polarized antenna as an example. The simulation results show that the number of the interferences can be more than the number of the array elements by utilizing the signal polarization domain information. Meanwhile, the gain of the desired signal can be maintained.

Key words： polarization sensitive array; space-frequency domain; anti-jamming; dual-polarized
