This study presents the methods and results of a new signal synchronisation algorithm for passive imaging by means of space–surface bistatic synthetic aperture radar with global navigation satellite system transmitters. The operating principles of the algorithm are described analytically. The results of the experimental testing with algorithms are presented and discussed. The performance of synchronisation results are calibrated by image inspection compared with theoretical counterparts. It is experimentally shown that the algorithm can handle data acquired both from GPS, GLONASS and Galileo with sufficient level of accuracy.
