Way to eliminate false method of targeting


Starting position are: (a coordinate system in Figure 2) T1 (59.66,0) km,herve leger skirts, T2 (59.66,103.33) kin, T3 (9.66, a 103.33). Taking into account the false alarm case, the positioning system to obtain location information shown in Figure 3. Fig. Figure 3 coarse positioning system device test results indicate the layout of circles in Figure 3,MBTシューズ 販売店, blue '×' symbol represents the true target position, the red 'a' represents the data without too many assumptions associated with the positioning results. It can be seen, multi-sensor positioning system 'ghost number is very large, in order to initialize the simulation conditions, for example,' ghost 'number 57. So many false targets such measures will not seriously affect the positioning accuracy of the system. Figure 4 shows the use of multi-hypothesis data association algorithm, when assuming the air has one,Beats By Dre Studio, two, three, four goals of the likelihood ratio of (the transfer p. 72) turn one, one, port 72 modern ... 24 Ray election noise. Therefore, the FLL bandwidth should be much more wide-bandwidth PLL, or reach the desired effects, usually one hundred kHz or so. 4 Conclusion and fractional-N PLL frequency-locked loop is a relatively new concept and technology, comprehensive reflection of modern electronic technology. From the experimental results, FNPLL can be better used in wireless communications and electronic warfare systems. But FNPLL LSI scores achieved by the integer part of the divider are larger, so FNPLI in broadband, a larger step,herve leger sale, phase noise, high performance synthesizer area radar applications have some limitations.

(Continued from page 46) can be seen, three more than the maximum likelihood target, in line with the actual maximum likelihood ratio corresponding to the measurement set is the real target position shown in Figure 5 the final result set target sales figure withdrawal 4 under the assumptions of the likelihood ratio group Huo Women Figure 5 Multiple Hypothesis Data Association Algorithm for the final result can be seen from the above results, when the number of targets is not significant. Multi-hypothesis data association algorithm in multi-sensor positioning system to eliminate the 4 Conclusion In the sparse layout of multi-sensor warning system, due to the presence of false alarms, even in the case of a single target can lead to all kinds of false targets associated with the appearance. In order to eliminate these false goals, this paper presents a multi-hypothesis testing based on data association method, can be seen from the above analysis, this association is the use of the echo from the target relative to 'cluster' of the computer simulation shows that to achieve . The method is feasible and effective. References 1 Kang Yao-hong. Financial theory and application data sets. Xidian University Press. 19972 Sun Zhongkang, Zhou Yiyu, He Lixing.
