火炮对空射击声靶的信号检测特性和传感器性能分析

The Analysis for Signal Measuring Characteristic and Sensor Capability of Gun Antiair Shooting Acoustic Target

根据空气动力学基本原理 ,超音速弹丸在空气中飞行时致使周围的空气发生压缩和膨胀产生激波信号 ,分析研究了弹丸激波信号的物理特性和频谱特性 ,以及检测其信号的传感器频响、灵敏度、过载能力、全向性等性能指标 ,为火炮对空射击声靶系统的总体设计提供了科学依据。

The aerodynamic theory shows that the shock-wave of flying super-sonic projectile is generated for the projectile compressing and expending its ambient atmosphere. This paper analyzes physical characteristic and spectrum characteristic of shock-wave and the sensor frequency response, sensitivity, overload and entire tropism capability of measuring shock-wave signal. This paper provides scientific basis for collective device of gun antiair shooting acoustic target system.
