In this work we use, analyzer, and compare eleven (11) detector FTIR spectral data collected with two different SLS detector sizes of 35μm and 40μm, and four different microsphere material structure types, namely, BTG (Barium Titanate Glass), SLG (Soda-Lime Glass), PS (Polysterene), and Sapphire, with sizes ranging from 90μm to 300μm. Based on the collected data considered in this work, it is shown that the size of the MWIR SLS detector has less effect on the microsphere-lens-enhanced detector overall spectral sensitivity improvement, than the microsphere lens structure type and size have. It is also shown, based on this overall performance area-metric that, in the 3μm-5μm spectral band, the sapphire material structure of size 300μm integrated on an SLS photo-detector of size 40μm outperforms the other considered ten (10) SLS MWIR photo-detectors enhanced with microspheres of different material structure types/sizes. The robustness to noise of the proposed overall performance metric is also shown here.","PeriodicalId":133804,"journal":{"name":"2015 National Aerospace and Electronics Conference (NAECON)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122961106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-coherent radar offers limited surveillance in clutter rich environments as compared to more complex and expensive coherent radar systems. The approach used leverages modern technology to affordably and effectively sample the radiated and received signals for further analysis using FFT-based Doppler processing. Track formation of moving targets are fundamental to any advanced radar and is a further focus of this paper. The marine radar hardware is modified to capture the transmitted and the received signals and the captured data was processed on an FPGA board. The cross-correlation and Doppler shift methods are used to find the velocity of the moving targets. In general, the coherent radars are very expensive, and our project will make them more affordable and reliable.","PeriodicalId":133804,"journal":{"name":"2015 National Aerospace and Electronics Conference (NAECON)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117144317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two major approaches in automatic modulation classification, namely the feature based approach and the decision theoretic approach. In our previous work, we have demonstrated the feasibility of using cyclostationary statistical features such as spectrum correlation function to perform modulation detection and classification for both RF signals and underwater acoustic signals. In this paper, we try to develop automatic modulation classification algorithms employing instantaneous features such as instantaneous amplitude, phase and frequency parameters. By extending previously developed features and evaluating appropriate decision metrics, we have been able to expand our modulation classification capability to 9 popular modulations including 2ASK, 4ASK, 8ASK, 2FSK, 4FSK, 8FSK and 2PSK, 4PSK, 8PSK. Thorough simulation results confirm the effectiveness of our proposed algorithm and threshold choices. The success of this approach also suggests a future research direction to combine statistical features with instantaneous features to provide a more accurate and more robust modulation identification algorithm.","PeriodicalId":133804,"journal":{"name":"2015 National Aerospace and Electronics Conference (NAECON)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126695615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
