Abstract
A system for correcting the effect of radome aberration on line-of-sight signals indicating target position. The aberration is in fact dependent upon both operating frequency and ‘angle-of-look’ and the essence of the present invention is to separate the corrections appropriate to each of these factors. The apparent line-of-sight signals are subjected to a frequency dependent amplification the result being used to address a store of error correction data. The apparent line of sight signals are also used to address a second store of error correction data and the two sets of correction data are added into the apparent line-of-sight signals to give true line-of-sight.
