Abstract在简要介绍AUV声学定位声纳接收机原理基础上,分析了CW脉冲信号在极性相关检测电路中的传输过程,建立了极性相关积分检测延时仿真分析模型。提出采用蒙特卡洛模拟方法获取检测延时的分布特征和统计参数的观点。实验结果表明蒙特卡洛模拟实验与硬件电路实验结果一致,对于解决随机性检测延时问题具有很强的能力。获得的结果可为AUV定位声纳检测门限的设定、声学测距和定位精度分析以及水声通信延时分析提供参考。
Other AbstractThe transmission process of CW pulse signal in the polar correlation circuit is analyzed after the acoustic positioning transceiver principle of the new deep ocean autonomous underwater vehicle(AUV) is been introduced briefly.The detection time-delay emulating analysis model of integral polarity correlation circuit is also established.The CW pulse detection time-delay directly affects the range precision of the acoustic positioning system,and the distribution character of time-delay is often estimated in the hardware circuit experiment which is operated difficultly.It is the first time that both distribution character and statistical parameter of the time-delay are obtained via Monte Carlo simulation.The experiment shows that the results of both the Monte Carlo simulation and hardware circuit method are in good agreement,and that the Monte Carlo simulation has a powerful ability to solve the detection time-delay problem.The experimental results are of some reference values to for the threshold voltage setting of AUV positioning sonar,acoustic ranging,the analysis of positioning precision,and the time-delay analysis of acoustic communication.
