7641 20251104123606.0 POSTER-2025-0048 Martínez Picar, Antonio Type II Burst in High-Resolution 2025 2025-10-27 We present high-resolution observations of a Type II solar radio burst captured with the Small Phase Array Demonstrator (SPADE). The high frequency/time resolution observations reveal fine-scale spectral structures within the radio signatures of a shock wave, one of the very important space weather phenomenon. Built on software-defined radio technologies, SPADE is a compact eight-element phased array developed by the Royal Observatory of Belgium and deployed at the Humain Radio-Astronomy Station. It recently underwent hardware and software upgrades that improve phase alignment and time synchronization across its elements. These enhancements extend operational coverage to 25 - 75 MHz with exceptional temporal and spectral resolution, enabling detailed characterization of drifting lanes and fragmented sub-bands within the Type II burst structure. This poster showcases SPADE's capabilities and highlights the potential of accessible, flexible instrumentation for advancing solar radio science and its application to operational space weather services. 2STCE_SUNTECH/ 2STCE_SUNTECH/ 2STCE_SUNTECH STCE solar radio observations phased array Marqué, Christophe Magdalenić, Jasmina Tassan-Din, Elisa European Space Weather Week 2025, Umeå, Sweden antonio.martinez@ksb-orb.be https://esww.coeo.events/live/item/fc7d77cb-7579-4f8f-9b22-955577f7c427 2842307 http://publi2-as.oma.be/record/7641/files/2025 MartinezPicar et al - esww2025 poster.pdf 22457 http://publi2-as.oma.be/record/7641/files/2025 MartinezPicar et al - esww2025 poster.jpg?subformat=icon-180 icon-180 23801 http://publi2-as.oma.be/record/7641/files/2025 MartinezPicar et al - esww2025 poster.gif?subformat=icon icon CPOSTER
