“…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.…”

The cooperative imaging of the bistatic radar is an important research topic for missile-borne radar detection. The existing missile-borne radar detection system is mainly based on the target plot information separately extracted by each radar for data level fusion, without considering the gain brought by the cooperative processing of the radar target echo signal. In this paper, a random frequency-hopping waveform is designed for the bistatic radar to achieve efficient motion compensation. A coherent processing algorithm for bistatic echo signals is designed to achieve band fusion and improve the signal quality and range resolution of the radar. Simulation and high-frequency electromagnetic calculation data were used to verify the effectiveness of the proposed method.
