WebRelated research is focused on the system design and optimization [5,6,7,8] and the development of accurate imaging algorithms [9,10]. Other studies are devoted to the non-ideal influences, including atmospheric effects [11,12,13,14]. However, orbital perturbations are rarely concerned, though satellites are certain to be impacted by ... WebIt shows that the Doppler effect is mainly related to the signal carrier frequency and the satellite orbit height. When the carrier frequency is larger, the satellite orbit height is lower, and the Doppler effect is more serious. For LoRa-LEO satellite communication system, the maximum carrier frequency is 928MHz, and
