Radio Direction-Finding Integrated Mobile Vehicle And Research On DF Accuracy

As the mobile Internet own a rapid development in recent year,That means wireless transmission shoud be more-secure,stronger-stability and fast-speed of the unless it will fail to match the demand of mobile communication terminal.How to strength wireless transmission is an urgent matter along with more and more high-tech crimes used wireless-tools.Currently,in our country,due to the wireless transmission management is under a primacy process;our first duty is make sure all the devices used wireless can work well,as our mainly regulation express:Justice、reasonable、 efficency and econimical. Advanced technological devices and technical method shoud be taken into daily management for all the radio managers。The radio monitoring, as the most commonly used in wireless transmission, should be concerned and improved its’performance and feature which worth to practical manipulate..At the beginning of this paper, the detection of the correlative interferometer system and present one monitoring method:"interpolation" are discussed.then aslo develops several key path to optimize the whole monitoring system. According to list five generally principles and features of the system,comparative data has been shown to prove the practical advantage of new method.Based on a actual case, through the whole sections of the monitoring and direction research, by using the interpolation method into the initial process, after finished system design final system intergration、validation、EMC、calibration and acceptance; we intend to optimize our system into an accuracy rate and eliminate bit error.With the higher accuracy, the monitoring will become more stable and easy to find out some suspicious signals then banked.Obviouslyit will not only enhance the enforcement of radio manager,but improving the whole system of national radio frequency spectrum management.Thanks to large number of experimental data and multi-vehicle radio monitoring case,an actual analysis is created to error-found、mechanism-problem and other related bit error.Based on this analysis, the optimization method has been verified.The conclusion is made that "interpolation" of improving measurement accuracy turly meet the expectation as well.
