箔条干扰是最常用的一种无源干扰，用来对付反舰导弹尤为有效。本文专门讨论适用于反舰导弹导引头识别箔条云的新方案。这一方案是建立在箔条云和舰艇去极化特性具有显著差异的基础上的。为此，本文首先论述箔条云的去极化特性，得出了不同分布箔条云的同极化截面积与正交极化截面积的比值，指出了即使在最不利情况下，对箔条云和对舰艇这一比值相差在６６Ｂ左右。本文提出的采用主极化天线通道和正交极化通道的１１通道信号处理方案正是利用了这一差异。本文最后对系统设计的有关问题进行了讨论。
Chaff jamming is the most common type of passive interference that is particularly effective against anti-ship missiles. This article is devoted to a new scheme for anti-ship missile seeker identification foil chaff cloud. This scheme is based on the significant difference in the depolarization properties of the chaff cloud and the ship. To this end, this paper first discusses the depolarization characteristics of the chaff cloud and obtains the ratio of the same polarization cross-sectional area and the orthogonal polarization cross-sectional area of the chaff cloud with different distributions. It is pointed out that even under the most unfavorable conditions, The ratio of cloud and naval vessels is about 66B. The proposed 11-channel signal processing scheme using a primary polarization antenna channel and an orthogonal polarization channel takes advantage of this difference. At the end of this paper, the related problems of system design are discussed.
