In view of the fact that there is currently no test equipment for the performance test of underwater acoustic modem communication, and the existing self performance test and evaluation based on the device itself to be test has insufficient objectivity, the invention designs the equipment and a method for testing performance of underwater acoustic Modem communication based on a simulated underwateracoustic channel. By constructing a real ocean underwater acoustic channel approaching simulator to test the communication performance of underwater acoustic Modem under different sea conditions, water depths, communication distances and mobility conditions, the equipment is capable of fully and objectively testing the performance of the test underwater acoustic Modem in a pool from a third partyperspective.
Description
technical field [0001] The invention belongs to the technical field of underwater acoustic communication, and specifically relates to a testing device and method for testing the communication performance of an underwater acoustic communication machine (that is, an underwater acoustic Modem), which is suitable for testing the performance of underwater acoustic communication equipment of various types and various interfaces. test. Background technique [0002] The ocean accounts for about 71% of the earth's surface area, and the space for human activities is gradually expanding from the land to the ocean. The 21st century is also called the century of the ocean. The ocean is rich in minerals and fish resources, and it is also a blue bridge and an important gateway for our country to connect to the world. Therefore, the development of the ocean has important political significance, civil value and military value. Whether it is seabed resource exploration, or submarine or under...
