ENABLING CLOSE RANGE MONITORING WITH THE ARECIBO 430-MHZ

RADAR
ABSTRACT:
The aim of this educational pro ject is to bring a lower atmosphere radar sensing capability to the AO. It will enable monitoring at once, all atmospheric layers below 100 km. It affords Electrical and Computer Engineering (ECE) students at UPRM with a unique research and educational experience. It aims to develop course materials in the areas of Electromagnetics and of Communications and Signal Processing. Selected results will be included in the section of "prior research" of a competitive proposal currently under development. The tropical troposphere contains 90% of the atmosphere by mass and it influences the dynamics of the atmospheric layers above. AO currently misses this entire region. Many UPRM­AO student interactions only happen in the context of field visits whose effectiveness, by design, are limited. The students mentored by the PIs will analyze the current radar system - microwave devices, cryogenic low noise amplifiers, data acquisition and data visualization. They will: design simple digital circuits to change attenuations and to control electronic protection circuits; run passive tests to evaluate performance with synthetic signals; run active tests to evaluate the lowest usable range and collect a small data base with observations; write a report and present the results at the annual gathering of the Industrial Affiliates Program (IAP) at UPRM's Job Fair (March 2011). The AO radar is the only instrument of its kind for this job. The results will impact atmospheric research in the tropics for years to come. The pro ject will serve to better educate many students in Puerto Rico. It has the potential to impact radar technologies deployed for monitoring in extreme EM interference and self-clutter environments.
