The problem of moving target indicator (MTI) filter design for radar systems with non-uniform (staggered) pulse repetition intervals is examined. The goal is to realise and then utilise a trade-off in the design of MTI filter between the conflicting requirements of high suppression of undesired signal (clutter echo) and minimal suppression of desired signal (target echo). To that aim, three design methodologies, namely, least squares, convex optimisation and min-max error, are studied. The numerical results indicate that the presented designs yield high-performance MTI filters which are easily applicable to a variety of operational scenarios. A ready-to-use source code for the design of suggested filters is also provided.

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.

“…This clutter is close to the target and moves slowly, but this clutter may be connected near the transmit pulse, which seriously affects target detection and tracking. Therefore, for the radar that can perform adaptive scanning detection in various complex environments, clutter suppression must be added to the signal processing process [2]. The recognition statistics for clutter suppression are mainly performed by clutter Doppler characteristics.…”

A large number of clutter interference signals were involved in radar echoes. Radar detection and tracking performance degrade when the signal-to-noise ratio of the echo signal is too low. Therefore, how to suppress clutter interference is a problem that is worth studying in designing. In this paper, the statistical characteristics of radar clutter were analyzed, and a clutter suppression method based on staggered MTI was proposed for the blind speed problem of traditional MTI filters. Simulation experiments verified the model and processing method of staggered filtering. The results indicated that the method improved the blind speed while effectively suppressing the clutter.
