Abstract :
A method (aimed at radar applications) of calibrating the sensors´ location, gain and phase uncertainties of a linear equi-spaced (LES) array is presented. This method can be applied to arrays with arbitrary geometry too. A technique to estimate the level of array´s error is developed also. Computer simulation and practical calibration example results illustrate that the method is effective
