摘要

在分布式电磁攻防对抗场景中，我方设备对敌释放干扰的同时，也极可能对己方电磁设备造成误伤，为此提出一种分布式同频干扰抑制架构与方法.通过对分布式同频干扰节点与授权接收节点之间时延误差与残余频偏进行建模，利用递归最小二乘算法求解模型系数，有效匹配高维信道和时频变化，并利用干扰参考信号完成分布式干扰重建与抑制.仿真结果表明，在归一化时延误差为0.2，归一化残余频偏为10

-4

时，本文所提出的分布式同频干扰抑制方法的干扰抑制能力相较于单节点同频干扰抑制方法提升13.1 dB，且残余干扰接近于底噪.

Abstract

In distributed electromagnetic countermeasure scenarios

our jamming transmissions directed against adversarial targets may in

advertently interfere with our own co-frequency electromagnetic systems. To address this issue

a distributed co-frequency jamming cancellation architecture and method are proposed. The method models the time-delay errors and residual frequency offsets between the distributed jamming nodes and the authorized receiving nodes

and solves for the model coefficients using the recursive least squares algorithm. This approach effectively accounts for high-dimensional channel and time-frequency variations. The reference jamming signal is then used for the reconstruction and cancellation of the distributed jamming. Simulation results demonstrate that under normalized timing errors of 0.2 and normalized residual frequency offsets of 10

-4

the proposed distributed co-frequency jamming cancellation method achieves a 13.1 dB improvement in jamming cancellation capability over the single-node approach

with residual jamming approaching the noise floor.
