| 摘 要： | 雷达信号的检测特性是根据目标回波的某种随机分布确定的,但实践证明雷达目标回波具有分形特性,即雷达回波是受非线性动力学系统控制的,随机性中又存在着某种确定性。根据雷达回波信号的分形特性,分析提出了雷达作用距离也具有分形特征。通过建立仿真模型进行实验,证明了所提理论的有效性,得到了雷达作用距离的分维数,对于修正雷达检测特性曲线具有一定的指导意义。

| Abstract: | The detection capability of the radar is determined by the random distribution of target echo.But in fact radar echo is fractal,that is,it is controlled by a nonlinear kinetics system and its distribution is randoin and also definite.The fractal feature of radar range is introduced based on the fractal feature of radar echo signal.By means of simulation models,a lot of simulation tests are made and the results are analyzed.The validity of conclusion is proved and the fractal dimension is given.The result is helpful for correcting the characteristic curve of radar detection. |
