Questions

What happens to the reflected signals received by each AR element when observing objects in a zone with a diameter of 4-5 thousand km?

They are relayed to ground reception and processing points directly when they are located in the same visibility zone, or / and through a network of neighboring satellites (two in their orbital plane and two in neighboring planes) during radar monitoring, for example, the Antarctic zone, from a point near Moscow or the Faroe Islands from the territory of England. These signals are retransmitted in digitized form without on-board phase and amplitude control, which allows each ground reception point to form one or more virtual radiation patterns (VDS) of the on-board receiving antenna and/or radiation patterns required for broadband communication applications for tracking objects.
