Propasal And Design For Multiple VHF FH Rradio Working On The Same Vehicle

With the development of communication construction for the information battlefield, the command communication vehicle in the tactic network and the aerial communication platform can be interoperable with multiple VHF radios on active service. However, when multiple different VHF FH radios on active service working simultaneously on the same platform with narrow space, there must have mutual interference among them and thus the communication effect will be affected. It is significant and very urgent to develop the FH Cosite filtering equipment to solve the mutual interference among multiple radios working in the same vehicle.Based on the tested result of 4 VHF FH radios mounted on the vehicle for field long distance FH communication test under FF and FH modes respectively, we seek the interference mechanism and main reason of multiple radios working in the same vehicle, conducting special subject test and design simulation to the key technical problems, analyzing the test data. Make comparative analysis to the flexibility and virtues and defects of each proposal. At last, we choose the best solution from the estimation of the project on economy, reliability, maintainability and measurability, etc.Based on the circuit simulation and analysis result of different filters, we conduct circuit design, reliability design, sample design and innovation, making high, low temperature, humidity and reliability environment test, verifying the developed effect through actual tested data and result. We make engineering innovation to the sample and field long distance test and user test to get the consummate engineering design and conduct mass production for the army.Research and solve the communication technique and method of multiple radios working in the same vehicle to realize designing and developing the FH Cosite filtering equipment on engineering for multiple radios working in the same vehicle so as to meet the need of interoperability in the tactic network transfer node for VHF FH radios on active service. It has important value and meaning in upgrading and innovating the entire military communication system and co-site communication.This paper aims at the communication test for multiple VHF FH radios working in the same vehicle, combining theoretical analysis and engineering practice, proposing the design method and implementation for multiple VHF FH radio working on the same vehicle.
