摘要
为正确设计低截获主动声纳的信号,在推导声纳截获概率因子方程的基础上,对低截获主动声纳信号,从低频、大时宽带宽积、复合码制、随机或非线性、时频捷变、能量效率等6个角度分析了信号的特征。结果表明,采用低频、宽带、符合编码脉冲串信号以及低功率发射是提高主动声纳低截获性能的重要手段。
To design signal of low interception active sonar exactly,on the basis of derive sonar interception probability factor equation,signal characteristics are analyzed from the view of low frequency,large BT product,compound code,random or nonlinear,cross section of time-frequency and energy ratio.The results demonstrate that main means of enhancing low probability of interception performance of active sonar are that signals with characteristics of low frequencies,wide brands,coded pulse chain and low power transmission ratio.
