This paper studies and presents the problem of scale effect of multistatic sonar. To study the detection performance of the multistatic sonobuoy system, the track-initiation probability is used as the detection probability of the target. The monostatic distributed and multistatic distributed detection modes are taken as examples. The influence of sonobuoy arrangements on sonar detection area is analyzed. The results of experiments show the method is available and compared with monostatic sonar system, multistatic system has scale effect. Moreover, the scale gain increases when the arrangement mode changes from triangular and square to hexagonal layout. Taking into account the flexible deployment of the multistatic sonobuoy system and the easy node expansion characteristics, we can make full use of the scale effect of multistatic detection, so as to effectively improve the capability for detecting submarine.
