摘要
声定向聚能系统是未来重要的反恐防暴非致命武器之一,系统的再现声频信号的频率特性、系统的指向性、系统远场声压级是重要指标,通过测试声定向聚能系统性能基本达到理想要求,并分析了误差原因。
Directional and energy-concentrated audio system is the key undeathful weapon the the antiterrorism. The frequency characteristics to the reproduction audio signal, system directivity and the far field sound pressure level of system are the important guidelines. The capability testing of the directional and energy-concentrated audio system is satisfied to the ideal requirement through the testing. The error is also analyzed.
