中文摘要：

针对以往作战模型的局限性,分析了潜艇被探测距离的影响因素,给出了一种较先进的潜艇被发现概率算法,其中考虑了以往模型没有考虑到的多种影响因素.并将潜艇宽带噪声和窄带噪声分开考虑,分别研究2种不同噪声下被发现概率算法.本方法具有一定的实用性.通过该算法,可以实现较为合理的潜艇被发现概率计算.

英文摘要：

Aimed at the limitation of t er-detection range was analyzed, and raditional combat model, influencing factors of submarine countan improved algorithm of submarine counter-detection probability was given in this paper. It included some influencing factors which were not been considered in traditional model. Different approaches to submarine counter-detection probability in two different conditions-broadband and narrowband noise, were studied separately. The method can be used in practice. With the use of this algorithm, a more reasonable submarine counter-detection probability can be achieved.
