Multi-target Detection Algorithm for MIMO Radar with Arbitrarily Distributed Array-Target Configuration

摘要

Adopting the eigen threshold(ET) criterion, a multi—target detection algorithm for MIMO radar with arbitrarily correlated observation channels is analyzed. Firstly, we derive the close-form of the eigenvalue, and the eigenvectors for the MIMO radar system having an arbitrary distributed array-target configuration based on power spectral density function, then, we establish the MIMO radar detector Adopting the eigen threshold(ET) criterion. The Method proposed avoids the Multidimensional Matrix inversion and alleviates the computational burden. Simulation results show that the correlation of the observation channels will reduce the detection performance. The algorithm can be utilized to compute and analyze the detection performance of a MIMO radar system for any given transmitter/receiver geometry, the computer simulation results also show that the MIMO ET has better performance than phase array detectors.
