| The domain of modern war has already extended to the five dimensions of land, sea, space, sky, and electromagnetism. To attain the optimum effect of battling, the multisensor systems are extensively adopted in the new generation of battling systems. Our research is mainly about sound detection and identification of the low altitude, super-low altitude targets, with the background of ground multisensor detection system. Based on the requirement of small size and low cost of sensors in the battleground, the article offers a small and practical design of microphone with higher-sensibility, and how to detect and identify the targets in the sky accurately and effectively. In addition, the article also discusses a further scheme to be improved, which can provide the reference for further research. |
