Pattern Synthesis of Sparse Phased Array Antenna Using Genetic Algorithms

  •  Rongcang Han    


Sparsely sampled irregular arrays and random arrays have been used or proposed in several fields such as radar, sonar, and ultrasound imaging. One method of pattern synthesis for sparse phased array antenna using genetic algorithms is introduced. We start with an introduction to genetic algorithms and then consider the problem of finding the best amplitude layout of elements in sparse arrays. The optimization criteria are then reviewed: creation of beam patterns with low main lobe width and low side lobes.
