摘要：
在大多数用于缓解间歇采样转发干扰（ISRJ）的技术中，对灵活干扰场景的适应性不足仍是一个未解决的挑战。基于匹配滤波系统的方法期望在匹配滤波之前或之后，结合基于先验ISRJ建模的抗ISRJ措施。由于ISRJ的部分匹配特性，其特征在匹配滤波过程中得以显现。因此，本文在匹配滤波过程中引入了一个称为波形域的扩展域。在该域上，建立了一种自适应匹配滤波模型，即波形域自适应匹配滤波（WD-AMF），以在不依赖预先存在的ISRJ模型的情况下解决ISRJ抑制问题。WD-AMF的输出包含一个自适应滤波项和一个补偿项。自适应滤波项包含波形域中的自适应积分结果，这些结果由自适应加权函数决定。该函数类似于一组带通滤波器，将积分函数分解为多个分量，其中一些包含干扰，而另一些则不包含。补偿项遵循一个集成准则，用于辨别积分函数中是否存在信号分量或噪声。然后将积分结果串联起来，以重构一个经补偿的匹配滤波信号输出。进行了仿真，以展示所提方法在各种干扰场景下抑制ISRJ的卓越能力，即使在缺乏预先存在的ISRJ模型的情况下也是如此。
英文摘要：
The inadequate adaptability to flexible interference scenarios remains an unresolved challenge in the majority of techniques utilized for mitigating interrupted-sampling repeater jamming (ISRJ). Matched filtering system based methods is desirable to incorporate anti-ISRJ measures based on prior ISRJ modeling, either preceding or succeeding the matched filtering. Due to the partial matching nature of ISRJ, its characteristics are revealed during the process of matched filtering. Therefore, this paper introduces an extended domain called the waveform domain within the matched filtering process. On this domain, an adaptive matched filtering model, known as the waveform-domain adaptive matched filtering (WD-AMF), is established to tackle the problem of ISRJ suppression without relying on a pre-existing ISRJ model. The output of the WD-AMF encompasses an adaptive filtering term and a compensation term. The adaptive filtering term encompasses the adaptive integration outcomes in the waveform domain, which are determined by an adaptive weighted function. This function, akin to a collection of bandpass filters, decomposes the integrated function into multiple components, some of which contain interference while others do not. The compensation term adheres to an integrated guideline for discerning the presence of signal components or noise within the integrated function. The integration results are then concatenated to reconstruct a compensated matched filter signal output. Simulations are conducted to showcase the exceptional capability of the proposed method in suppressing ISRJ in diverse interference scenarios, even in the absence of a pre-existing ISRJ model.
