As an example using the passive sonar, it calculated the quality factor of passive sonar using the sonar equation. The sound field was calculated under different depth and range using multiform hydrographic conditions. The isoline of passive sonar quality factor was marked out on the sound field. The isoline also represented the passive sonar range. The simulation results showed that hydrographic conditions had important effect on passive sonar range. At the same hydrographic conditions, the permissible drawdown of passive sonar had important effect on passive sonar range. Thus, according to the hydrographic character, the passive sonar range could be improved by selecting suitable passive sonar permissible drawdown.
