Data to generate Fig. 22: Optimized Sparse...
URL: https://data.nist.gov/od/ds/mds2-2595/Fig22_OptimizedSparseArrayBeamPattern.csv
Periodicity in the beam pattern, here calculated and reported in Fourier space (u=sin(theta)cos(phi), v=sin(theta)sin(phi), where theta is the elevation angle and phi is the azimuth angle), is eliminated by the use of the randomly perturbed spatial sample locations of the sparse array. These simulated data show the outcome of using the sparse array labeled "After" in dataset "Fig21_SparseArrayBeforeAndAfterOptimization.csv" and provides a comparison to this randomized perturbation to the regular sampling output given in "Fig20_GratingLobesDueToSparseSamplingGrid.csv".
