Abstract

Passive radar experiences a significant problem called multipath clutter. The Batch version of the Extensive Cancellation Algorithm (ECA-B) is an efficient method for clutter mitigation. With the increase in signal bandwidth, a greater number of segments is required to cancel the clutter across the entire frequency range. This affects the processing rate, detrimentally weakening and modulating the signal from low-speed targets. Thus, this paper proposes a method that uses ECA-B to process both reference and echo signals in the frequency domain. This method not only reduces the amount of calculation required but also avoids weakening and modulating the target signal, which is spread across many segments. The simulated and experimental data results confirm the correctness and validity of the proposed method.

无源雷达频域杂波抑制的批量扩展抵消算法

无源雷达会遇到一个重要的问题，即多径杂波。批处理版本的扩展抵消算法(ECA-B)是一种有效的杂波抑制方法。随着信号带宽的增加，需要更多的段来消除整个频率范围内的杂波。这会影响处理速率，有害地削弱和调制来自低速目标的信号。因此，本文提出了一种利用ECA-B在频域同时处理参考信号和回波信号的方法。这种方法不仅减少了所需的计算量，而且避免了目标信号的削弱和调制，因为目标信号分散在许多段上。仿真和实验结果验证了所提方法的正确性和有效性。

期刊介绍： Journal of Radars was founded in 2012 by the Institute of Space and Astronautical Information Innovation of the Chinese Academy of Sciences (formerly the Institute of Electronics) and the China Radar Industry Association (CRIA), which is located in the high-end academic journal and academic exchange platform in the field of radar, and is committed to promoting and leading the scientific and technological development in the field of radar. The journal can publish Chinese papers and English papers, and is now a bimonthly journal. Journal of Radars focuses on theory, originality and foresight, and its scope of coverage mainly includes: radar theory and system, radar signal and data processing technology, radar imaging technology, radar identification and application technology. Journal of Radars has been included in domestic core journals and foreign Scopus, Ei and other databases, and was selected as ‘China's high-quality science and technology journals’, and ranked the first in the category of electronic technology and communication technology in the ‘Chinese Core Journals List (2023 Edition)’.
