Angle estimation in bistatic MIMO radar based on reduced-dimension subspace reconstruction
Peng Ma · Journal of Circuits and Systems · 2013
According to the principles and echo model of the bistatic MIMO(multiple-input multiple-output) radar,a novel angle estimation algorithm of departure direction and arrival direction based on reduced-dimension subspace reconstruction is proposed.The algorithm that only requires one-dimension search can avoid the high computational cost within the two-dimension Music(2D-Music) algorithm and needs fewer training samples.By means of Monte Carlo simulations,the estimation variance on different SNR,snapshots and array elements are simulated.Simulations are consistent with the theoretical analysis and verify the usefulness of the algorithm.
