<p>PURPOSE:To uniformly provide an antenna received power by obtaining an array plane coordinate system search covering area during perturbation of an antenna, by correcting the perturbation of a beam in this area which is arranged so that its stack ratio (ratio of overlap between adjacent areas) is constant, and irradiating the beam. CONSTITUTION:An electron scanning radar beam control device is composed of a search beam dimension calculating part 1 for calculating dimensions of a beam in a search covering area upon maximum perturbation with respect to each antenna surface, through an array plane coordinate system, a search beam dimensions storage part 2 for storing the dimensions of the sear beam, a search covering area setting part 3 for converting the search covering area in a horizontal bow reference coordinate system into the array plane coordinate system at predetermined intervals in consideration with the perturbation so as to determine the inside and the outside of each beam, a search beam dimension reading part 4 for reading a beam in the search covering area, a perturbation correcting part 5 for calculating horizontal north reference coordinate values of the beam, and an antenna I/F part 6 for delivering beam irradiating data to the antenna. Accordingly, it is possible to give such an advantage that the power received by the antenna may be made to be uniform even during perturbation of the antenna.</p> |
