Ambiguity Resolution in Amplitude-Monopulse Systems Using Broad-Beam Patterns
Miguel Poveda-García, José Luis Gómez‐Tornero
Abstract
In this letter, the use of flat-top broad beams is proposed for the improvement of the robustness against direction-of-arrival (DoA) ambiguities in amplitude-monopulse systems, if compared to the conventional use of narrow tilted beams. Oscillations of the monopulse function outside the field-of-view are eliminated, thus suppressing false detections created by signals coming from outside the angular range of interest. Theoretical and experimental results using a modulated leaky-wave antenna, which synthesizes a broad-beam at 15 GHz, confirm this improvement.
