为了满足航空反潜指挥控制系统对声纳浮标搜潜效能进行评估的需要，建立了声纳浮标的作用距离预报模型。首先根据声纳方程，推导出了声纳浮标作用距离的预报模型。然后建立了模型中各个参数的计算模型，并进行分析。最后，针对特定的海洋环境，在一定检测概率和虚警概率条件下，根据作用距离的预报模型仿真分析了主被动声纳浮标的作用距离，为机载声纳浮标的作用距离预报提供了有价值的参考。

To satisfy the needs of airborne anti-submarine warfare command and control system for evaluating the effectiveness of sonobuoys in submarine searching,a model for predicting the operating range of the sonobuoys was established.Firstly,the prediction model was induced according to the equation of sonar.Then,calculation models for each parameter in the operating range prediction model were established and analyzed.At last,simulation was made to analyze the operating ranges of active/passive sonobuoys by using the prediction model under the condition of specific ocean environment with certain detection probability and false alarm probability.The results can provide a valuable reference for operating range prediction of airborne sonobuoys.
