复杂目标角闪烁序列的混沌特性

The Chaos Feature of Glint Series for Complex Targets

角闪烁是寻的制导的主要跟踪误差源.国内外诸多学者对角闪烁进行了大量的理论和实验研究,主要探讨角闪烁与RCS的统计依赖关系,其一认为角闪烁与RCS有较强的负相关性,另一种看法是它们之间不相关,但又非独立.这种对角闪烁本质的认识尚处于探索中,本文从混沌动力学角度,分析角闪烁序列的非线性,并以混沌特征判据对角闪烁序列进行分析,提出复杂目标角闪烁序列具有混沌特性.

Glint error is one of the primary error sources in the homing guidance of radar tracking on extended targets.Many scholars have done much theoretic and experimental research on glint,mainly discussed on the statistical dependence between glint and RCS. One opinion supports that the relation between glint and RCS has a negative relativity, the other one is that there is no relativity, but not independent. This understanding on the nature of glint is still explored. In this paper, we analyze the nonlinearity of the glint series, study the glint series based on the criterions of chaos feature, and then conclude that the glint series have chaos feature for complex targets.
