An Extension to the Theory of the Performance of Airborne Moving-Target Indicators

The performance of an airborne moving-target indication (MTI) system, designed to detect moving ground targets, is shown to depend upon the video autocorrelation function of the ground return, both with and without a target. The pulse-to-pulse video autocorrelation function is derived, and from it are obtained formulas for MTI cancellation and moving-target enhancement. Results are given only for a square-law detector.
