摘 要：This work proposes mitigating emissions vulnerability by utilizing a new method of optical communications at LOS visual ranges reminiscent of flag semaphore. Tactical QR code communications streaming digital data through optical signaling has the potential to provide tactical communications at a moderate range, allowing critical communications to be relayed to and from off-ship platforms. Additional technological advances can be used to overcome current range, security, reliability, and throughput barriers. This project demonstrates how a combination of essential technical capabilities can be used to establish a QR code communications system as a potentially useful approach for tactical operations.
