Experimental comparison of Starlink and OneWeb signals for passive radar
Given the limited available information about Star-link and OneWeb signals but the relevant capabilities that they may provide, this work is focused on the experimental acquisition and comparison for passive radar applications of the user downlink signals transmitted by these emerging satellite constellations. In order to received these signal, an updated version of the SABBIA system has been developed with satellite tracking capabilities and enhanced instantaneous bandwidth to enable the digitization of a complete transmission channel. Based on the analysis of the received Starlink and OneWeb signals in terms of the ambiguity function, both constellations are considered suitable as complementary potential illuminations of opportunity for high-resolution passive radar applications.
