Computer-Automated Evolution of Spacecraft X-Band Antennas
- Tuesday, 01 June 2010
A document discusses the use of computer-aided evolution in arriving at a design for X-band communication antennas for NASA’s three Space Technology 5 (ST5) satellites, which were launched on March 22, 2006. Two evolutionary algorithms, incorporating different representations of the antenna design and different fitness functions, were used to automatically design and optimize an X-band antenna design. A set of antenna designs satisfying initial ST5 mission requirements was evolved by use these algorithms.
