摘要:
为提高雷达系统对欺骗性干扰的抵抗能力,提出一种基于极化捷变编码技术和匹配思 想的抗干扰方法。通过发射极化捷变信号,将回波的幅度和相位与目标的先验信息进行匹配, 从而提高系统在干扰环境下对该目标的检测能力。MATLAB 仿真表明: 该方法可在低至0. 4 dB 的信干比下检出目标,具有较高的实用性和稳定性。
Abstract:
In order to improve the ability of anti-deception in radar system,an anti-deception method is proposed based on the polarization agile coding technology and matching idea. By transmitting polarization agile signals, the amplitude and phase of the scattered waves are matched with the prior information of a certain target,and the ability to detect the target is improved in the interference environment. The MATLAB simulation results show that the target can be detected even when the signal to deception ratio( SDR) is lowered to 0. 4 dB,a nd the method is practical and stable.
