Brief description of the sum and difference signals of a radar of the monopulse type antenna, in order to estimate the parasitic phase introduced between these signals by the circuits manufacturing process of formation of the sum and difference channels.

摘要

The process according to the invention applies, for example, the estimation of the phase parasitepsentre the sum and difference of azimuth, consists in calculating the expressions s . S and d, s for various successive measurements carried by the radar, and then to calculate the expression s (k1) - s (k - 1) . Of (k) for different successive instants k - 1, k, k1 and to carry out an operation of the result of this expression for different instants k, it being understood that the radar antenna scans in azimuth and that the radar wave emise is polarized in a circle, the azimuth and elevation monopulse 29 receiving, respectively, that one of the types of circular polarization: the right or left. / p & & p & application to the tracking radar of the monopulse type antenna.
