主 题:Simulated annealing(SA) Sparse planar arrays 3D underwater sonar imaging Beam pattern Optimization
摘 要:This paper proposes an optimized simulated annealing(SA) algorithm for thinning and weighting large planar arrays in 3D underwater sonar imaging *** optimized algorithm has been developed for use in designing a 2D planar array(a rectangular grid with a circular boundary) with a fixed side-lobe peak and a fixed current taper ratio under a narrow-band *** extensions of the SA algorithm and the procedure for the optimized SA algorithm are *** examples of planar arrays are used to assess the efficiency of the optimized *** proposed method achieves a similar beam pattern performance with fewer active transducers and faster convergence ability than previous SA algorithms.
