APPARATUS FOR SIMULATING OF SENSOR SIGNAL OF PASSIVE SONAR

摘要

PURPOSE: A sensor signal simulator of passive sonar is provided to accurately simulate a sensor signal of the passive sonar in a space like indoor. CONSTITUTION: A sensor signal simulator of passive sonar comprises a transmission transducer(110), a reception hydrophone(130), a first guide(151), and a second guide(153). The transmission transducer creates sound wave under the water surface within a water tank. The reception hydrophone receives the sound wave under the water surface. Three or more reception hydrophones are arranged on the circumference of the bottom plane of an imaginary right circular cone. The first guide supports the transmission transducer. The second guide supports the reception hydrophone.
