We demonstrate the ability to extract the wing beat frequency in real-time. Such processing affords a method of readily discriminating between animals and other flying objects such as micro-unmanned aerial vehicles. The timing waveforms used for sampling and integration can have a significant impact on the fidelity of the data that can be captured and on the response time of the system to detect and analyse animals in motion. This work paves the way for future research in support of target classification and conservation ecology.","PeriodicalId":102625,"journal":{"name":"2012 International Waveform Diversity & Design Conference (WDD)","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115439476","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}

The primary comparison is between a traditional range and bearing measurement model and one that additionally considers amplitude of return using a radar cross section (RCS) target model. Using the UK-PHD filter to handle the nonlinear measurement models, it is shown that using an RCS target model results in more accurate state estimates and a reduced number of track dwells, thus devoting more time to searching for targets. Additionally, the use of an RCS model also results in improved clutter rejection further increasing the observed differences in track accuracy and refresh rate.","PeriodicalId":102625,"journal":{"name":"2012 International Waveform Diversity & Design Conference (WDD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120952188","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}

Heretofore this type of capability has been reserved for much larger systems such as the JSTARS. Previously small liteweight SARs featured only a single channel and only displayed SAR imagery.

Frequency-domain likelihood ratios (LR) are obtained via response distribution modeling and statistical parameter estimation on a per-sub-carrier basis. Then the generalized likelihood ratio test (GLRT) is performed on a composite LR. We propose to enhance this approach via adaptive selection of OFDM signal's sub-carriers to improve the detection performance; exploiting frequency diversity of the target scene by complementing the GLRT-based detection with frequency profile matching. This approach, when applied to a software-defined system, will provide for cognitive radar functionality.","PeriodicalId":102625,"journal":{"name":"2012 International Waveform Diversity & Design Conference (WDD)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128109750","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}

This repetitive time gating of the raw signaling waveforms employed at physical level of communications, radar or sensor systems can sometimes largely remove interference, but leaves a waveform remnant that will often be insufficient to permit satisfactory restoration of the entire signal waveform through simple interpolatory filtering. If the interference is periodic the requisite gating of the digitized signal can be treated as periodic nonuniform decimation. We undertake restoration using the “alias unraveling” approach, introducing a digital filter design of the sampling pulse which leads to significantly better conditioning of the unraveling matrix, and affords a very considerable extension of resilience to interferer duty cycle.","PeriodicalId":102625,"journal":{"name":"2012 International Waveform Diversity & Design Conference (WDD)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127957716","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}

In a military context, particularly in a contested electromagnetic spectrum (EMS), RF spectrum management could occur through the use of adaptive artificial intelligence. The use of the EMS for command and control can be disrupted by a variety of threats even when cognitive RF techniques are employed. This potential for disruption means that human intervention may be needed at times in order to maintain an adequate level of command and control. This presentation will provide an overview of the dual-process framework of human decision making and how it would relate to training humans for this kind of intervention. This framework indicates that decision making by humans is composed of a blend of two complementary systems or modes of operation: an analytical system and an intuitive system. The analytical system permits abstract reasoning and deliberation, but it is constrained by working memory capacity. In comparison, the intuitive system is based on situational pattern recognition and is not constrained by working memory capacity. In this presentation it will be suggested that the intuitive decision-making system, because it is based on pattern recognition, is ideal for training humans to intervene when command and control is disrupted.","PeriodicalId":102625,"journal":{"name":"2012 International Waveform Diversity & Design Conference (WDD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132686934","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}
