Abstract:

The Imaging theory, retrieving algorithm and principle of thinned array of two dimensional synthetic aperture radiometer are presented, and based upon simulated annealing algorithm, two kinds of optimized thinned array are obtained. One is the array restricted in the circle area with rotating, and the other is the array restricted in T-strip area with the restriction that the antennas must be on the regular grids. Experimentation and simulation results proved that these kinds of thinned array are practical.

Key words: 2D synthetic aperture radiometer    Simulated annealing    Thinned array
