Abstract :
An efficient algorithm for calculation of the radiation integral is described. The process is presented in the form of a crosscorrelation which is carried out by utilising the fast Fourier transform. Applications to a plane-polar geometry and to the reflector antenna are considered and the results of simulations are presented as validation of the process.
