摘要
随着低空开放地逐步深入,"黑飞"问题日益影响着正常的军事训练和日常经济活动,迫切需要一种手段来应对。基于声学设计的思想,提出了一种监测低空空域内飞行器的声探测手段,并就目标特征、声目标检测及系统抗风噪声进行了初步的探讨,以期为中国的低空监测技术发展提供新思路。
With the progress of opening low altitude airspace,＂ illegal black flights＂ problem has affected the normal military training and daily economic activities, so the means that can deal with it become a pressing need. Based on acoustic design idea, a acoustic method that can detect aircraft in low altitude airspace is presented, and a preliminary discussion is made on wind noise, target characteristics of acoustic target detection, so as to provide clear references for the development of lower airspace monitoring technique.
