武装直升机的声场测试

Acoustic Field Measurement of Armed Helicopters

该文根据国内外反武装直升机武器的发展，提出了一种以被动声探测引信技术为核心的雷、弹合一的武器系统，并讨论了直升机噪声的产生机理，介绍了声探测引信系统的工作过程和设计构想。根据设计构想，设计出了直升机声场的测试方案，采用边长为１ｍ的正方形阵列，对直升机噪声进行了外场测试，并给出了部分实验数据。通过对测试结果的分析，证明了全声探测体制或声／红外复合探测体制的反直升机武器的可行性。

According to the development of armed helicopters at home and abroad, this paper advanced a weapon system of smartmine, with a passive detecting acoustic fuze, as its main part and introduced the work principle and design problem. A project of acoustic field measuring of helicopters was set up, and its ground measuring test was completed. Some experimental data have been put forward. The analysis of the experiment results shows that the acoustic detecting system or acoustic/infrared rays detecting system are practicable in the anti-helicopter weapon systems.
