[0002] As a passive electromagnetic interference device, inflatable corner reflector is widely used in interference countermeasure tests. Inflatable corner reflector can be used for dilution, centroid and confusion interference methods. The offshore test area of ​​inflatable corner reflector is usually far away from the offshore range, so monitoring its position and status requires the use of more stable and reliable communication methods to meet the needs of special test scenarios. During the interference countermeasure test, the inflatable corner reflector will float with the ocean current after being deployed at sea. In order to verify the test results and recover the equipment, its position needs to be tracked in real time. In addition, after the inflatable corner reflector is deployed, the internal air pressure may change due to the ambient temperature, external force and its own material problems.
