Anti-helicopter Mine System And Its Integration

Arming helicopters play an indispensable role in the battle for air supremacy nearby the earth. The anti-helicopter mine will be the most important weapon system to defend arming helicopter hedgehopping in future war. Based on the research of the national defense pre-researching project-"The Fuse Technology of Smart Mine", the warning system has been improved, and the integration of the arming system, the servo system and the communication system has been finished. Also, the software and hardware designs of the passive acoustic detection system have been completed on the basis of sub-band algorithm.Based on the previous research, the warning system is improved, and with the method of multi-threshold zero-cross ratio, the software of the improved warning system is finished. The integration of the improved arming system, the servo system and the communication system has been done, and the software of the integrated system has been completed.In order to improve SNR and the anti-jamming ability, the detecting technology of anti-helicopter mine based on sub-band has been introduced. With the need of real-time and accuracy, high performance floating DSP is used as core processor and the circuit design of acoustic detection system has been completed. A second-level Bootloader has been created in order that the system can run solely after the system is electrified, and the code has been burned into the flash.After the design of hardware and software, the static experiment has been done to test the performance of system, also the test data has been analyzed.
