Aerospace Multi-platform Network And Data Link Simulation

Data Link (DL) is the processing, exchanging, distributing system for information. DL links the sensors, command and control center, weapon platforms and armies in the battlefield. Network Centric Warfare (NCW) combines the detecting system, command and control system and weapon system in the land, sea, air and space, which is in virtue of communication and information cells. The multi-platform network and DL technology, which takes the Airborne Information Platform (AIP) as the center of command and control, plays an important role in NCW and determines the modern warfare.This paper makes an introduction on Joint Tactical Radio System (JTRS), which represents the new generation of DL technology, and analyzes the two key parts: Tactical Targeting Network Technology (TTNT) and Wideband Networking Waveform (WNW).Based on the network simulation software OPNET, this paper studies the simulation and the structure of multi-platform network and DL technology, which takes AIP as the center of command and control. According to Link16 widely used by American army, the multi-platform DL is organized using Time Division Multiple Access (TDMA). The well-known simulation software OPNET is employed to simulate and model the multi-platform network. A co-simulation environment is constructed between external real video stream and OPNET kernel by use of the ESD module. Finally, the network stability and effectivity is analyzed with regard to TDMA time slot, jam, modulation and the packet capacity of transmission channel.
