Frequency Hopping Radio Integrated Testing Technology Research

Tactics Radio Interactive Network is an especial important military communication network.Radio plays a key role in the network above-cited. As a mainly equipment for tactics communications,it is nearest approach the war,so the maintenance for the radio affects the battle effectiveness directly.With the growing of information-based in our army,our army has equipped most radios,mainly include medium -long wave radios,general digital resisting ultrashort radios,handy ultrashort radios,on-back ultrashort radios,general multiple channels radios,general high-speed digital radios etc.Because of multiple working bands and the flop frequency systems,the maintenance is difficult and the cost is very expensive.Currently,the methods are not enough to maintain the radios.If you maintain the radios with the base-measure instruments,you may need large amount of the base-measure instruments and the measure system being makeup of the base-measure instruments is complex,large and high-cost.It could not satisfy the fast measuring.Some integrated measure instruments have not flop frequency function,some instruments are not identical with the radios about modulation and demodulation system,and they can only measure fixed frequency performance.When the radio working in the flop frequency mode,they can not measure transmit and receive performance index of the radio,and can not measure the performance of flop frequency digital transmitting.They can not measure and maintain the radios completely.The thesis is based on GJB238A-1997《the methods to measure tactics -frequency modulation radio》and GJB3434-1998《the methods to measure flop frequency radio》,aimming at the problem how to measure and maintain the flop frequency radios currently,we adopt the technique of modulation domain analysis,multiple system modulation and demodulation based on software radio,flop frequency signal generation and synchronization, which solves these problems that the oneness of modulation and demodulation that the general integrated measure instruments,they could not measure the flop frequency communication and flop frequency instantaneous performance directly.Whereas you may measure the receiving performance index,the transmitting performance index,the flop frequency digital transmitting index,flop frequency pattern of the radio in working state with our instrument,you may detect many kinds of radios. Furthermore,for reducing cost and volume,the thesis analyses every part of the measure instrument detailed from theory and engineering practice and we adopt new technique,decide a best scheme by comparing performance and price.By the way we innovate some traditional techniques and acquire an active effect.Finally we research the integrated measuring instrument applied to the of measure the flop frequency radio successfully,solving the engineering problem to measuring and maintaining the flop frequency radio in Tactics Radio Interactive Network。...
