Description
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 35 - 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.
