The chaos feature of glint series for complex targets

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.
