背景和装甲目标毫米波被动探测统计特性研究

根据背景和装甲目标不同的毫米波辐射机理,采用不同的统计方法得到了背景和装甲目标的不同统计特性。针对背景的不均匀性造成的背景辐射特性的非单一性,提出了采用假设检验的方法得到背景的统计分布；针对装甲目标难以得到统计分布的特点,提出了以目标信号复杂度为特征量的装甲目标辐射特性的统计方法。为毫米波被动探测地物及装甲目标识别方法的研究提供了必要的理论依据,具有切实可行的指导意义。

Study the statistical properties of passive millimeter wave detection background and armored target

This paper obtained the different statistical characteristics of background and armored target based on the different millimeter wave radiation mechanism of them. Due to the uneven background, the background radiation characteristics is not a single value. Therefore, to obtain the statistical distribution of the background, we presented a method based on hypothesis testing. Meanwhile, due to the armored targets difficult to get the statistical distribution, we proposed a new statistical method for armored target, which named as signal complexity. The statistical method proposed in this paper provides the necessary basis for the research of recognition algorithm of background and armored target. in passive millimeter wave detection field. At the same time, these statistical methods have practical significance for passive millimeter wave detection field.
