A Distributed Detection Scheme for Multiple Monostatic Radars

The body of distributed detection theory is based on the common assumption that all sensors test the same resolution cell at the same time. However, for multiple monostatic radars that are far from one another, it is unreasonable to assume they have common resolution cell grid. Meanwhile, it is economically appealing to use existing radars to fulfil the distributed detection. Thus, we proposed a simple data association method to map local resolution cell grids to the global cell grid of the fusion center. Considering the time of different radar sweeping a given volume may be different and the interesting target may be moving, we present a mixed summation fusion rule to overcome the harmful effect of cell grid overlap and time-asynchronization. Results show that our method far outperforms the single radar´s detection performance and can improve the position estimate of target Therefore, it is feasible
