Abstract:
In order to resolve the nonlinear optimization problem of TDOA Locatio n, a hybrid method that employs a modified immune algorithm and a Chan algorithm is proposed. The modified immune algorithm is a consociation of genetic algorit hm based on chaotic initial population and floating point code with modified imm une operator that reduces the computational complexity by providing faster conve rgence. Simulation results show that if the population size is big enough, the a lgorithm is robust and can find the coordinates of near optimization. It has a h igher accuracy than Chan algorithm and a faster convergence than genetic algorit hm.
