本文简要介绍有效地应用于浅海声释放器的时间自相关积累接收机的原理,分析了系统适应于时空变信道和抗多途效应和噪声的性能,并对系统的虚警概卒、检测概率进行了估算。现场实验和理论分析说明系统的性能是优越的。自相关积累方案既可推广于复杂的水下数字数据传输的一些领域,也可应用于主动声呐的某些探测速率要求不高的方面。
This paper briefly introduces the principle of time-dependent accumulation receiver effectively applied to shallow-sea sound releasers, analyzes the performance of the system in adapting to space-time variable channel and anti-multipath effect and noise, and analyzes the system’s false alarm probability, detection probability Estimated. Field experiments and theoretical analysis show that the performance of the system is superior. The autocorrelation accumulation scheme can be generalized in some fields of complex underwater digital data transmission, and also can be applied to some aspects of unsound detection of active sonar.
