Özet

The design of moving target indicator (MTI) filters with nonuniform interpulse periods is studied through the least square and min-max filter design methodologies. A trade-off between the contradictory objectives of maximum possible clutter suppression (maximum stopband attenuation) and minimum desired signal attenuation (minimum passband ripple) is established by the introduction of a weight factor into the design. The weight factor enables the adaptation of MTI filters to different operational scenarios such as system operation under low, medium or high clutter power.
