Abstract :
A backtransform method for correcting active phased array antenna position errors has been evaluated. An equivalent set of excitations is computed from the measured far-field and compared to the ideal excitations. The difference is corrected for and an improved radiation pattern is obtained. A number of simulations with different errors have shown that the sidelobe level can be considerably improved.
