| 摘 要： | 在高频条件下,亮点模型是对回声信号的良好近似描述,以此为物理基础,在时域上对仿真和实测的目标回声信号进行了相关分析,计算了回声信号的能（量）宽（度）比和幅度分布函数。结果表明,几何形态不同的目标的回声信号在上述三方面有着明显的差别,因此可用作判别目标几何形状复杂程度的一种判据。

| Abstract: | Based on that a highlight model is a good approximate description of echoes at high frequencies,correlation analysis was made and ratio of energy-width and distribution of amplitude were computed for simulated echoes and measured echoes in time domain. The results show obvious differences exist on the three aspacts mentioned above for echoes from targets of different geometries,and therefore,they can be used for judgement of the complexity of the targets geometries. |
