摘要
浅水主动声引信应用较少,主要由于混响干扰较强,信号不易被检测。主动声引信多用于深水反潜。根据目标多普勒频移特性,提出了一种在浅水条件下,高频主动声引信的布阵方案。同时针对引信角度覆盖扇面,进行了布阵性能计算与优化选择,并对矩形阵元进行了初步设计。
Active acoustic fuze is used less in shallow water, for there is much reverberation and the signal is hard to be detected, so active acoustic fuze is often used for anti-submarine in deep water. Based on Doppler frequency shift,this article sets up an arrays scheme for active acoustic fuze with high frequency in shallow water. For complete covering, this article calculates the angles and chooses the best. The sizes of all arrays are also calculated.
