Observations & Results
A research-focused view of project observations, published transit-scan context, and future public data products.
Selected Results
Each result is summarized rather than republishing complete paper pages.
What is shown: A raw spectrum stage in the H I observation workflow.
Why it matters: It places SDR acquisition and FFT-based spectral extraction at the center of the platform. The project is presented as a complete measurement chain, not only as a reflector build.
Source: Project lecture material; related signal-processing workflow is described in the 2025 IEEE publication.
What is shown: Calibration and first survey products from the project lecture.
Why it matters: Transit observations connect time/frequency measurements to sky structure as Earth rotates through the beam. Published scans should be interpreted as normalized signal strength or relative H I response unless an absolute calibration is explicitly stated.
Source: Project lecture material; published transit-scan context - IEEE Antennas and Propagation Magazine, 2025.
What is shown: A project concept linking survey observations, calibration context, and sky/velocity interpretation.
Why it matters: The model \(T_B(\alpha,\delta,v_{\mathrm{LSR}})\) is the scientific endpoint used to connect sky position, H I intensity, and radial velocity. This figure should not be read as a complete calibrated 3D brightness-temperature cube by itself.
Source: Project lecture material.
What is shown: A real H I line example included in the lecture material.
Why it matters: The line profile is the observational signature that lets students connect antenna temperature, calibration, velocity, and Galactic hydrogen science.
