Station arrangement strategy of TDOA/AOA location system based on genetic algorithm

CRLB of location error produced by TDOA/AOA location algorithm is derived.An algorithm searching for the best station arrangement strategy of TDOA location system is proposed,which is based on genetic algorithm.The fitness principle should be contented is that the best station arrangement strategy makes the average CRLB of location error least.The encoding of node position and fitness function in GA are researched.Algorithm to search the best station arrangement strategy is proposed based on GA.In the simulation experiment part,the searching-best algorithm based on GA is simulated under different situation.
