Microwave staring correlated imaging based on 3-dimensinal randomly distributed antenna array

In this paper, we demonstrate a new three dimensional (3D) randomly distributed antenna array for microwave staring correlated imaging. Its construction method is presented and the imaging model based on it is established; In order to characterize its random spatial arrangement of array antennas quantitatively, 3D random distributed entropy is defined; Based on the optimal model of maximizing the distribution entropy, optimal random distribution of 3D antenna array can be obtained by using genetic algorithm. Numerical simulation confirms its validity of the proposed 3D antenna array in improving its stochastic characteristics of radiation fields and achieving better imaging results.
