Data Processing Technology Of Multi-Radars Network

Data Processing Technology of Multi-Radars Network were studied in this paper based on the task of multi-radar netting, which includes the survey of multi-target tracking, error registration, data association and target state estimation, et al.At first, implement the coordinate transform and introduces the coordinate system error used to correct this error and its implementation principle. The formula for correcting system error of two radar is also put forward. After simulation, this arithmetic can correct estimate the system error.About data association, this paper based on the description of plot-plot association, plot-track association and track-track association, new conception of static divided-area and dynamic divided-area is introduced and theirs correlation arithmetic. The two divided-area arithmetic can reduce the computable quantity and the error rate of data association. The system practical implementation capability is enhanced. At last the paper bring forward the conception of sequence filter.All the methods mentioned in this paper are used to acquire a realizable data flow of software. And the course of data processing technology of multi-radars network is simulated in C++ Builder.
