In this paper, we propose a method based on evolutionary computations for joint estimation of amplitude, Direction Arrival and range near fleld sources. We use memetic computing in which the problem starts with global optimizer ends up local flne tuning. For this, Genetic algorithm Simulated annealing as while Interior Point Algorithm rapid optimizer. set Mean Square Error fltness evaluation function deflnes an error between actual estimated signal. This is optimum derived from Maximum likelihood principle. It requires only single snapshot to converge does not require any permutations link it angles found previous some other methods. The e-ciency reliability proposed scheme tested basis Monte-Carlo simulations its inclusive statistical analysis.
