Angle-measurement error of a coherent monopulse radar signalresulting from imbalances between in-phase and quadraturecomponents, as well as between sigma and delta channels, arecorrected in a simple procedure. No correction is needed for I,Qimbalances in the time domain [1]. Instead, a postintegrationcorrection is performed. This reduces the number of calibrationoperations of the monopulse signal by a factor X, 2 ≤ X ≤ N (N isthe number of DFT samples), depending on the degree of filtering.It also reduces the number of numerical operations necessary forthe production of the correction term by a factor of three. A firstorderrder estimation is made of the residual error after correction, dueto bias and image sidelobes.
