Master Level Sonar Analyst Trainer (MLSAT)

The Instructor mounts either a 28-channel, primary acoustic source tape on a 1" reel-to-reel tape replay unit or a two-channel auxiliary acoustic source tape in a digital audio tape cassette unit, or both, at the Instructor Station. From the possible channels of acoustic data, the Instructor chooses two (2) sets of four (4) channels for transmission to the Student Station for analysis by the student. The Instructor can assign either of the two (2) groups of signals to either of the two (2) student groups. He can also aurally monitor any of the acoustic data channels on headphones. The instructor can communicate with any individual student, either of the two (2) groups of students, or all of the students through an intercom. In addition, the Instructor can select and monitor at his station and student station spectrum analysis video and audio without the student's knowledge and monitor their progress. He can also project this video data onto a projector in the classroom for display on a screen mounted on the classroom wall and broadcast the associated audio through a classroom speaker.
