In article the analysis and a rating of influence not identity of orthogonal channels on efficiency of application of the equaliser of pulse jam which algorithm of action realizes double discrete is spent transformation Hartly with simultaneous regeneration of the struck components of a useful signal in capstral planes. The rating of influence on an overall performance of the equaliser was spent in view of peak and phase not identity of orthogonal channels. Peak and phase not identity it is simulated by a deviation of peak and phase characteristics of channels from ideal. Job of the equaliser was simulated for a case of influence on coherently-pulse radar nonsynchronous pulse handicapes, which casual in the image will amaze from one up to three discret range of the certain frequency pack. For a parameter of efficiency is accepted difference between quantity erroneous regeneration the module of spectral density of signals of an echo - signal, at absence and at presence not identity. It is shown, that not identity quadratures results in decrease in efficiency of application of the equaliser, personsенно in difficult jam to conditions.
