Bistatic Radar Cooperative Imaging Based on Complementary Random Waveform

Sensors (Basel). 2023 Feb 25;23(5):2577. doi: 10.3390/s23052577.

Abstract

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.

Keywords: bistatic radar; cooperative imaging; motion compensation; random frequency-hopping.
