Analysis of Joint Channel Coexistence Time at Space-Diversity Radio Reception of Meteor Reflections

This paper examines the possibility of joint reception of radio reflections from the same meteor trails simultaneously at two spaced receivers. A refined simulation of a joint reception area (JRA) of meteor radio reflections on the basis of a diffraction theory of oblique scattering of radio waves off ionized meteor trails is performed for radio links of moderate (500 km) and medium (1000 km) lengths. The obtained results may be particularly useful for territory planning of meteor burst communication (MBC) networks with the spatial division of subscribers (SDMA technology). The simulated JRAs also characterize an interception probability of messages. This knowledge is especially important in designing highly secure MBC, such as meteor key distribution systems, intended for the creation of two identical copies of a shared secret key at both sides of the meteor radio link.
