The research related to the U.S. army soldier radio waveform （SRW） is analysed. An overview of the SRW waveform is given， focusing on the technical regime of the waveform， and a detailed analysis of the protocol stack and the network architecture is presented. The SRW is designed hierarchically from the physical layer， link layer and network layer and the application in relevant radio station （AN/PRC-152 radio station， AN/PRC-154 radio station， AN/PRC-155 radio station） is discussed in depth. Through the analysis and research of SRW waveform and related radio application discussion， it can provide relevant research results and reference basis for the new type of soldier self-organized network waveform design， and promote the development of new system of soldier self-grouping network radio development by leaps and bounds.

As the role of satellite navigation systems in war continues to improve， it faces an increasingly complex battlefield electromagnetic environment， in order to ensure accurate and efficient transmission of timing and positioning information， and seize the information advantage， the military powers in the world continue to research and develop navigation war-related technology and its equipment， and its successful application to the construction of a new type of satellite navigation system and navigation jamming equipment， to improve the battlefield survivability of satellite navigation systems and the battlefield denial capability of navigation jamming equipment. The navigational warfare related overview and status role are introduced， the capacity status and development trend of navigational war are analyzed in detail， and the suggestions for the development of navigation warfare are given， the relevant research achievements can provide reference for the navigation development.
