Bistatic sonar operations on modern submarines are classified into cooperative and non-cooperative operations. In the cooperative operation, an active signal of a friendly ship is used and the source information is known a priori. In the non-cooperative operation, an active signal of the enemy is used, which makes it difficult to acquire the source information. The source information consists of the range, speed, course, and frequency of ping, which gives advantage to operating bistatic sonar. This paper suggests a novel method of estimating the source information with geographic information in the sea and the single-ping of the enemy. The source range is given using one geographic point. The source speed, course, and the frequency of the enemy's source signal are given using two geographic points. The performance of the proposed method is validated through simulation studies.
