Using a moving aerial platform to detect and localise a low probability of intercept radar

IET Radar, Sonar and Navigation, 2017
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
