摘要:
声定位技术在军事和民用领域中都具有广泛的应用。文中设计了一种基于GPRS无线传输网络的声目标定位系统,数据采集和控制由以TMS320VC5402为数据采集处理器和MC35为GPRS无线传输模块的硬件系统完成。软件系统完成数据的预处理、目标识别和定位。同时,鉴于时延估计算法和传声器阵列的选择是影响定位精度的主要因素,选取四元十字面阵作为传声器阵列的设计方案,针对非平稳信号提出了基于短时傅里叶变换(STFT)谱图的瞬时频域相关时延估计算法,并进行了重点分析,最后通过实验验证了系统的可行性
Abstract:
The acoustic localization technique has been widely applied in civil and military aspects.An acoustic target localization system based on GPRS was designed in this paper.The hardware of system is built on TMS320VC5402 microprocessor and MC35 module.Software of system consists of data process,target recognition and localization.As the same time,the design of 4-element cross array and a time-delay estimation algorithm for non-stationary signal based on short time Fourier transform(STFT) spectrogram were proposed,and emphatically discussed.Experiment results verify the effectiveness
