摘要：
In this study, the problem of detecting and finding the location of a low probability of intercept (LPI) radar is investigated. A method based on using two electronic support antennas mounted on a moving aircraft is proposed and it is proved that the phase difference between the signals received by the two antennas can be used to detect and localise an LPI radar. In addition, the effect of the aircraft random displacements on the proposed method performance is discussed and a modification to compensate for unwanted motions is introduced. Simulation results show the effectiveness of the method for detecting very low signal-to-noise ratio signals, and the proposed method performance is compared with the short-time Fourier transform method.
