During operations in Bosnia and Afghanistan, the Predator UAV required support of 50 to 100 people ranging in skill set from ground pilots, to mechanics, to the guards and cooks who supported the flight operation personnel. The affordability of UAV systems will be reduced if support personnel can be eliminated as a dominant recurring cost factor. Full autonomy through the injection of onboard intelligence is a solution to affordability. For the past decade, teams have been pushing the state of the art in intelligent aerial robotic behavior as part of the International Aerial Robotics Competition.","PeriodicalId":385351,"journal":{"name":"Final Program and Abstracts on Information, Decision and Control","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114863978","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}

Targets with a radial velocity relative to the radar site are detected by the Doppler component of the received radar signal. A network of OTHRs with overlapping coverage provides for the detection and tracking of targets irrespective of target velocity. When tracks are formed by each radar in the network, multi-radar track fusion is necessary to clarify the surveillance picture. In addition, multipath ionospheric propagation conditions may yield multiple tracks for each target and for each radar. In this paper, a multi-radar multipath track fusion algorithm (MRMPTF) is outlined, extending the single radar multipath track fusion (MPTF) algorithm previously developed. The impact of OTHR track registration errors is discussed, and the equivalence of alternative OTHR track fusion architectures is shown.","PeriodicalId":385351,"journal":{"name":"Final Program and Abstracts on Information, Decision and Control","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131782751","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 paper gives details of an error table compensator system that uses a VLSI chip incorporating a transversal filter programmed as a wideband differentiator, some additional on chip circuits, and a lookup table that is stored in external memory. The 10 GOPS transversal filter differentiator chip was designed and fabricated in a 0.35 /spl mu/m CMOS process, has programmable tap weights, and can operate at a maximum clock rate of 200 MHz. The results of this paper show that this error table compensation system is capable of providing up to 13 dB improvement in the dynamic range of typical high speed A/D converters. This may result in more reliable detection of weak signals of interest.","PeriodicalId":385351,"journal":{"name":"Final Program and Abstracts on Information, Decision and Control","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122341232","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}

These systems are fully specified by a candidate set of parameters, whose elements are, a rate matrix for the Markov chain and a vector of Poisson intensities for the observation model. Further, we suppose these parameter sets can switch according to the state of an unobserved Markov chain and thereby produce an observation process generated by time varying (jump stochastic) parameter sets. Given such an observation process and an assumed collection of models, we compute a filter whose solution is the estimated probabilities of each model parameter set explaining the observation. By defining a new augmented state process, then applying the method of reference probability, we compute matrix-valued dynamics whose solutions estimate joint probabilities for all combinations of candidate model parameter sets, and values taken by the indirectly observed state process. These matrix-valued dynamics satisfy a stochastic integral equation with a Lebesgue-Stieltjes integrator. Using the gauge transformation techniques, we compute robust matrix-valued dynamics for the joint probabilities on the augmented state space. In these new dynamics the observed Poisson process appears as a parameter in the fundamental matrix of a linear ordinary differential equation, rather than an integrator in a stochastic integral equation.","PeriodicalId":385351,"journal":{"name":"Final Program and Abstracts on Information, Decision and Control","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117261785","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}
