摘要
针对从空间目标RCS序列丰富的目标特征信息中提取有效特征非常困难,在空间目标RCS序列的研究中引入非线性理论。分析空间目标RCS序列产生混沌的机理,运用最大Lyapunov指数方法研究空间目标RCS序列,并探讨空间目标RCS序列的混沌特性。计算结果表明,与旋转目标相比,三轴稳定目标RCS序列较复杂和不规则,这与实际分析的情况相符合,证明了该方法的有效性。
It is difficult to extract the useful character information from the RCS which contains a lot of information of space object.The nonlinear theory is introduced into the research of RCS series of space object.The Mechanism that the RCS of space object produces chaos phenomenon is analyzed.The maximum Lyapunov exponent is used to analyze the RCS,and research on the chaotic is undertaken.The result shows that the RCS of the triaxial stabilized target is more complicate and irregular than that of rotated object.The result conforms with the actual analysis of the situation and proves the effectiveness of the method.
