Optimization of Fourier Plane Coverage of Antenna Arrays for SPORT
The fidelity of image reconstruction of SPORT depends on samplings in the Fourier transform domain of the scene performed by its antennas array. Research in this paper aims at finding the optimal layout of the receiving elements which is fitting for SPORT. Simulated annealing is applied to finding solutions for N=8,10,12,14. The simulation results show that centers of gravity of optimized antenna arrays are situated on center of the circle. Spatial frequency domain is covered evenly by the sampling points after rotation of the optimized antenna array. Moreover, the redundancy of baselines is minimized. The length values of the baselines of the optimized antenna array are also evenly distributed on the interval 0,1.
