A Review of RF and Free-space Optical Combined Tactical Communication Technology
Informatization and intelligence capabilities have become key elements for defeating the enemy in a strong adversarial battlefield environment.Tactical data link,whose security and robust ability directly determine the operational efficiency of various branches of the military,is the key to the information exchange between various combat units/plat forms.At present,there are mainly two ways to establish communication on the battlefield:radio frequency(RF)and free space optical(FSO).The article discusses these two communication methods and briefly compares the tactical performance and development trends of some international RF data links and FSO communication systems.Based on the above analysis results and the latest research on microwave photonics technology,a RF/FSO combined tactical data link system has been con-ceived,and some discussions and prospects have been conducted.
