PERFORMANCE INCREASING METHOD THROUGH DYNAMIC GROUPING/PRECODING IN A MIMO RADAR SYSTEM WHICH APPLIES A PRE CODING METHOD TO A GROUPED RECEIVER

摘要

PURPOSE: A performance increasing method through dynamic grouping/precoding in a MIMO radar system is provided to reduce signaling overhead and computational complexity and to increase detection probability.;CONSTITUTION: An SINR(Signal to Interference-plus-Noise Ratio) value is stored in all receivers according to the movement of a target in a MIMO radar system. A receiver is dynamically grouped based on the received SINR value(S100). A precoding method is applied to the grouped cooperative receiver(S200). A data process of a CPU, signaling overhead of a back hole network, and calculation complexity are reduced after the precoding of receiver. SINR of the receiver is increased.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S100) Receiver dynamic grouping; (S200) Precoding method; (S300) Signaling overhead/calculation complexity reducing
