Method for improving the performance by dynamic grouping/precoding in the MIMO radar system

摘要

invention is MIMO (Multiple Input Multiple-Output, MIMO) radar system on a dynamic grouping / precoding relates to performance improvement methods through. MIMO MIMO radar radar technology is far apart from each other to improve the performance of the radar by using spatial diversity (spatial diversity). Distributed MIMO radar system is not very practical, but in fact the need to cooperate with each other for signal processing, all or a large number of radar transmitter and receiver cooperate. The present invention dynamically updates (update) the signaling overhead by applying a precoding scheme in the receiver as well as the grouping (signaling overhead) and the computational complexity of the receiver group and cooperation so as to cooperate only in a limited number of the receiver via the receiver grouping ( computational complexity) provides a way to increase the probability of detection to reduce. ;
