Spectral Coexistence of MIMO Radar and MIMO Cellular System

Key Points

This work aims to design a precoder for a MIMO radar that can coexist spectrally with a MIMO cellular system.
Developed two precoding methods: conventional switched null space projection (SNSP) and switched small singular value space projection (SSSVSP).
Evaluated the impact of each method on radar target localization capability with varying numbers of antenna elements.
Analyzed spectrum sharing capabilities to achieve zero or minimal interference.
SSSVSP provides better radar localization compared to SNSP under certain conditions.
Increasing the number of radar antenna elements significantly enhances performance.
Spectrum sharing achieved with minimal interference using SSSVSP.

Abstract

This paper details designing the precoder of a MIMO-radar spectrally-coexistent with a MIMO cellular system. Spectrum sharing with zero or minimal interference is achieved by using, respectively, the conventional switched null space projection (SNSP) or the newly proposed switched small singular value space projection (SSSVSP). Loss in radar target localization capability due to precoding can be compensated by using SSSVSP instead of SNSP to some extent but increasing the number of radar antenna elements is more effective.
