摘　　要：在双基地声纳方程的基础上，进行作用距离的估算和分析比较。在特定的情况下，计算表明，双基地声纳作用距离比单基地声纳作用距离可提高４～８倍。China's shipping industry has foreseen the need of information concerning bistatic sonar and, in the absence of information in the open literature,supports our research on estimating its operational radius. Our calculation, partly based on tests,shows that its operational radius is much higher than that of mono -static sonar.For our estimate,we take conservatively transmission -loss,TL,to be very serious as given in eq.(3).For bistatic sonar,TL=TL1 +TL2 is related to other standard terms in sonar technology (SL,NL,DI,DT, TS)as shown in eq. (2).In Table 1,the last column gives the ratio of bistatic operational radius to mono -static operational radius.This ratio varies from 4 for working frequency of 3 000 Hz to 8. 2 for 300 Hz.
