基于双DSP的反直升机智能雷弹系统设计

针对具有更快飞行速度的新一代武装直升机投入使用，重新设计了反直升机智能雷弹的总体结构。智能雷弹采用模块化设计，预警模块、通信模块、战斗部和随动机构由单片机控制，声探测与数据处理模块由两片DSP控制。为满足智能雷弹的低功耗要求，完成了预警模块的硬件设计；为满足反直升机智能雷弹实时性能的要求，以两片高性能浮点DSP和CPLD为核心，完成了声探测与数据处理模块的硬件设计，以及各个模块之间数据接口设计。通过仿真实验表明，基于双DSP的反直升机智能雷弹满足实时性和定位精度的要求。

The Design of Anti-Helicopter Smart Mine System Based on Dual Digital Signal Processors

Considering the new generation of armed helicopter with faster speed, the overall structure of the anti helicopter smart mine is redesigned. The smart mine is designed by using modular design. Early warning module, communication module, warhead and follow-up mechanism are controlled by single chip microcomputer. Acoustic detection and data processing module is controlled by dual DSP. To meet the requirements of smart mine of low power consumption, the hardware of the early warning module is designed. To meet the requirements of anti helicopter smart mine with the real-time performance, the hardware of the acoustic detection and data processing module are completed by two pieces of high-performance floating-point DSP and CPLD as the core. All module interfaces are designed too. Through the simulation experiments, it shows that the anti helicopter smart mine based on dual DSP meeting the requirements of real-time and precision.
