    摘要:

    针对大型舰船平台中电磁环境复杂,不同设备之间互相干扰的问题,研究了射频干扰对消技术。分析了射频干扰对消的数学原理、系统模型,并对对消性能与幅度误差、相位误差的关系进行分析。通过分析自适应滤波器的原理,结合大型舰船平台X波段雷达的特点,提出了一种射频干扰对消技术。该方案采用最小均方误差(LMS)算法,通过仿真验证了该对消方案算法实现的可行性。仿真结果表明,该射频对消系统的对消比可达40 db左右,能够实现高对消比。

    Abstract:

    Aiming at the problem of complex electromagnetic environment and interference between different devices in largescale ship platform, the technology of RF interference cancellation is studied. The mathematical principle and system model of RF interference cancellation are analyzed, and the relationship between cancellation performance and amplitude error and phase error is analyzed. By analyzing the principle of adaptive filter and combining the characteristics of Xband radar of large ship platform, a kind of radio frequency interference cancellation technology is proposed. The scheme uses the least mean square error (LMS) algorithm to verify the feasibility of the cancellation scheme. The simulation results show that the cancellation ratio of the RF cancellation system can be up to about 40 db, and the high cancellation ratio can be achieved.
