Evaluation of Blind-Speed Mitigation and Moving Target Filtering in Surface-to-Air Missile Control Radars

Le Dinh Tuyen

Abstract

This study aims to develop an intuitive and user-friendly simulation interface that supports the evaluation of blind-speed mitigation techniques in pulse-Doppler radar systems. By enabling users to conveniently adjust key input parameters—specifically the pulse repetition period and transmitted frequency—the interface facilitates the visualization and assessment of corresponding output characteristics. Using MATLAB, the amplitude–velocity characteristic (ACX) curves of the Moving Target Detection (MTD) filter bank are analyzed across operational modes of a surface-to-air missile (SAM) control radar. Through the examination of blind-speed suppression by varying the pulse repetition period, the proposed tool allows users to effectively evaluate the improvement in blind-speed coverage and understand the influence of pulse-repetition-period modifications on the occurrence of blind speeds. The results demonstrate the usefulness of the developed interface in supporting radar-system analysis, educational training, and engineering design related to MTD processing.
