The model proposed in an attempt to find out physical bases of object perception during echolocation. It is shown that echolocational perception can be provided with correlational treatment of corresponding signals. The character of objects is determined by the comparison by echo probing accepted in the given cycle with typical distortions remembered in the course of individual experience of the animal. The distortions take place during the reflection of the probing impulse from these or those objects. "Binding" of the objects according to distance may be carried out by using the choice of typical distortions for corresponding correction of the copy of probing impulse, serving as a bearing signal of distance correlometer. The response of correlometer to the echo from correctly perceived target increases. The block-scheme of such correlation perception during echolocation is given. Performance of some experiments allowing to check and refine the model considered.
该模型旨在探寻回声定位过程中物体感知的物理基础。研究表明，回声定位感知可通过对相应信号的相关处理来实现。物体的特征由给定周期内接受的回声探测与动物个体经验过程中记忆的典型失真进行比较来确定。这些失真发生在探测脉冲从这些或那些物体反射时。根据距离对物体进行“绑定”可通过选择典型失真来对探测脉冲副本进行相应校正来实现，探测脉冲副本用作距离相关仪的方位信号。相关仪对正确感知目标的回声的响应会增强。给出了回声定位过程中这种相关感知的方框图。还进行了一些实验以检验和完善所考虑的模型。
