SDR-based radar system for meteor detection


a.) Did the abstract tell you the three things I said it should? 
Yes
– The abstract gave enough detail to know the paper is about using radio waves to monitor atmospheric events & detect meteors.
– It explains what the authors/researchers did to conduct their research using a DAQ (Data acquisition) system based on software defined radio.                                                                                                      – The authors created the DAQ system so yes. 

b.) What seems to be the research question(s) they were trying to answer ? The question the research was trying to answer was whether they could create a DAQ system that could be used to monitor atmospheric events, detect meteors, & ultra high energy cosmic rays (UHECRs)

What  method(s) did they use to answer the question(s) They used the experimental research method.

How credible do you think the paper is?
I think this paper is fairly credible as there were nine authors from various tertiary institutes around the world, with Helio Takai for example having published 258 different papers and having 6,317 citations. They did experiments that related directly to the question they set out to answer and found they need to upgrade/change some of the components/software to detect the UHECR’s  which seems credible to me.

Did you agree, or not, with what they wrote in their conclusion? Why?
I agreed with what they wrote in the conclusion  as it fits with what I understand about SDR’s already, for example that they need an accurate realtime clock for certain use cases e.g. signal triangulation.

Briefly describe two things that you learnt from the paper.
I learn’t about another Windows based SDR software other than SDRsharp. I learn’t that the escape velocity from the Solar System is 72km/s while the escape velocity from earth is 11km/s.

In no more than 250 of your own words.
This paper describes a technique for detecting Meteors & Ultra High Energy Cosmic Rays using a software defined radio. The method used is to detect television signals being reflected from the ionized trails left by meteors & the extensive air showers (EAS) left by UHECR’s, which are very similar to the meteor trails. The reason for doing this research is to find a more cost effective & reliable way of detecting compared to the current techniques which require large arrays of detectors spread across huge areas. In the conclusion they found that the technique will work but requires some refinement to increase accuracy.
