摘要

摘要: 基于收发同时工作体制下的收发耦合干扰抑制问题在目标模拟系统中的重要性, 阐述了鱼雷电磁引信目标模拟系统的设计方案和工作方式, 建立了在收发同时工作下的耦合模型, 提出了利用自适应对消来实现目标信号和耦合干扰信号的实时分离, 并对模型和算法进行了仿真计算, 重点研究了自适应对消算法参数的选择对收发耦合干扰抑制有效性的影响。仿真结果表明, 在参数选择合理情况下的自适应对消方法能有效地解决收发耦合干扰抑制问题, 同时考虑自适应对消的实时性和稳定性, 采用递推最小二乘算法比最小均方算法更合理。

Abstract: Considering the importance of receive-transmit coupling interference suppression problem in simultaneous transmit-receive operation for the target echo simulation system, a coupling model of torpedo electromagnetic fuze for target echo simulation system is established in the condition of simultaneous transmit-receive operation. An adaptive cancellation algorithm is proposed to achieve real-time separation of target signal and coupling interference. The model and algorithm are analyzed via simulation and calculation, laying emphasis on the influence of parameters selection for the adaptive cancellation algorithm on the performance of coupling interference suppression. Simulation results show that the coupling interference suppression could be solved by the proposed algorithm if the parameters are selected properly. With respect to real-time property and stability of adaptive cancellation, the recursive least squares algorithm behaves better than the least mean square algorithm.
