“…Compared to single radar detection, multi-radar collaborative detection can not only obtain more observation periods but also obtain the characteristics of different dimensions, such as frequency character [3], polarization character [4], space character [5], etc., which is an important development direction for stealth target detection in a complex electromagnetic environment. According to the varied detection angles and radar working frequency bands, multi-radar cooperative detection mode can be divided into spatial cooperation and frequency band cooperation, to obtain the benefits of spatial diversity [6,7] and frequency diversity [8,9]. The former realizes target detection and recognition by jointly processing information for multiple detection angles to reduce the probability of misjudgment in single-view detection.…”
