The combination of moving target indicator MTI and coherent integration filters can provided velocity filtering with advantages that neither technique can provide alone. These techniques are evaluated as a special case of a transversal filter which lends itself to analysis using matrix algebra. This approach gives a simple, easily understood insight into the effects of weighting the input radar data. The resulting matrix equations are evaluated and the results are plotted for some special configurations. The computer programs which were written as a part of this research are not restricted to these configurations nor to the type of clutter spectrum that is assumed. It is shown that the performance of coherent integrators in a coherent noise clutter environment cannot be predicted with a concise analytical expression. In particular, the weighing of the input data and the covariance matrix of the interference determine the integrator performance.
