The Design And Implementation Of Correspondence Frequency Acquisition System For Military Wireless Radio

As the key equipment of the command tools, the military radio is now being widely used in the modern warfare and also as a carrier, the data, voice, characters and other information are transmitted by radio through it. Just with the military wireless radio, the operational intention of the commander could be successfully communicated on time. In the mean wile the right decision and judgment also can be made at the first time according to the report of the latest situation of the warfare of the military wireless radio. In general, it is difficult to win a war without a smooth communication from the ancient times to the present, so the military wireless radio can be seen as an important guarantee of it.The frequency of the wave velocity jump for the Military frequency-hopping radio is becoming faster and faster, how fast the Sync Info can be established is the key of the privacy of the information; how fast the Sync Info could be established is depend on the efficiency of frequency acquisition of the information. So the efficiency of the frequency acquisition is one of the most important parts among the military information technology.This design is using the DSP (Digital signal processor) chips TMS320F2812as the processor to deal with the frequency acquisition rely on its own acquisition units of the event-manager module. It uses acquisition unit to capture the arriving times of two continual rising edges of receiving waveform. The difference of these two times is the cycle of receiving waveform we can use it to calculate the communications frequency and send it to the military wireless radio for synchronizing.Therefore, for meeting the requirements of the modern military communication affairs, making the achievements of the most efficient frequency acquisition of the info for the Sync Info’s establishment and the smooth communication would provide favorable conditions for the outcome of the war.
