【摘要】 本文讨论了有源声呐设计中的三大要素(声呐波形、声呐信道和接收机)之间的相互关系,着重讨论有源声呐信道(包括混响、传播和目标散射过程的信息模型),提出用统一的推广散射函数和相干函数来描述,并通过对信道输出相关函数以及匹配滤波输出的分析指出这两个函数的物理意义和测量方法,最后还讨论声呐最佳波形和最佳接收机设计的基本原则。更多还原

【Abstract】 The relation between three main factors (waveform, channel and receiver) of active sonar is discussed in this paper. The models of active sonar channel, which include marine reverberation, signal propagation and object scattering in sonar processes, are described, by generalized scattering function and generalized coherence function. Physical significance and measuring method of both function are explained with aid of channel output corralation function and matched filter output. Finally, the fundamental principles for design of the optimum waveform and the optimum receiver are presented.更多还原
