Error Correction Based on Genetic Algorithm for Digital Array Radar

In this paper, a method based on genetic algorithm is presented for error correction of digital array radar. This method first corrects the amplitude and phase errors of the receiving channel with group-checking at a time by the far-field calibration source, and then realizes the same correction of the transmitting channel by the interior correction. So it is convenient and fast to implement the amplitude and phase errors correction of the digital array radar. The simulations illustrate that the method is feasible and valid
