【摘要】 应用混沌动力学方法分析和计算了激光雷达回波信号的混沌特征参数,包括关联维,Lyapunov指数及局部可预测性。证明激光雷达回波信号具有有限的关联维,正的Lyapunov指数及短期可预测和长期不可预测的特点。运用实测数据验证了激光雷达回波信号具有混沌特性,这一结论为激光雷达的目标检测开辟了新思路。更多还原

【Abstract】 The chaotic dynamic approach is used to analyze the chaotic characteristics of the laser radar backacatter,and based on the observed data,the chaotic character parameters,including correlation dimension,Lyapunov exponent and local predictivity,are counted.Results show that the laser radar backscatter possesses some natures of the chaotic process.This conclusion leads a new method in the target detection of laser radar.更多还原
