Due to its potentially catastrophic effects, the prevention and detection of runway incursion is a very important aim for any airport. This aim represents a multi-dimensional issue that can be faced only with a multi-dimensional and multi-task approach. From a measurement point of view, a fundamental role in this context is played by the sensors network employed in the airport area. Developing a cooperative sensor network able to carry out a real time, accurate and reliable information about the airport ground status is mandatory. This work presents the activity developed by the authors focused on the improvement of the measurement characteristic of a sensor system employed in an Italian airport for the surveillance of stop bars areas. A method, based on a classifier, which permits to extract new and high-level information from the sensor signals, is proposed. This method allows to classify the type of transiting object, discriminating therefore the intrusions from the authorized passages. In this way, by a simple retro fitting to existing system, a significant improvement of the safety of the traffic control process has been achieved","PeriodicalId":188809,"journal":{"name":"2006 IEEE International Workshop on Measurement Systems for Homeland Security, Contraband Detection and Personal Safety","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124893807","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 proposed optical processor technology employs wavelength division multiplexing (WDM) encoding and technologies that enhances secure communications for a wide bandwidth of operation. In our example of two-channel approach, four adjacent ITU optical WDM channels are used as optical carriers. Each pair of optical carriers directs RF information of one receive/transmit beam. The optical channels feed a 3-bit programmable dispersion matrix (PDM), which performs true-time delay processing. The PDM is based on three optical delay lines, arranged in a binary or ternary configuration. Each delay line consists of four fiber-Bragg gratings (FBG). The separation between FBG increases by multiples of two for each delay line. Beampatterns are characterized in receive and transmit modes for RF signals in 0.5-1.5 GHz range and are obtained for target angles of plusmn70deg. The measurement results demonstrate the simultaneous processing of two RF-beams and the squint free nature of the beamformer. The scaled up version of beamformer to large array size and its simultaneous multiple-beam processing will be presented. We would also describe a potential architecture of an all-optical delta-sigma modulator that can be implemented in a digital transmit/receive beamformer","PeriodicalId":188809,"journal":{"name":"2006 IEEE International Workshop on Measurement Systems for Homeland Security, Contraband Detection and Personal Safety","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122068605","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 authors propose and qualify here image based people motion estimation: the idea is to measure the \"motion level\" of the people through the analysis of images grabbed with common video cameras or with an infrared thermal imager. Cameras working in the visible wavelength range usually have a higher resolution than thermal cameras and are much cheaper, due to this reasons they are often preferred for the estimation of people motion in case of events held during the day (i.e. with stable lighting conditions); nevertheless thermal cameras have various important advantages in some applications, as during concerts; in these cases, in fact, lighting is mainly projected on artists, leaving the audience in an almost completely dark atmosphere. In this scenario the use of a common camera often leads to poor quality images; for this reason in this research a thermal camera has also been used, in order to acquire sequences of infrared images of the jumping crowd. In this way more reliable results can be obtained even in case of very low lighting","PeriodicalId":188809,"journal":{"name":"2006 IEEE International Workshop on Measurement Systems for Homeland Security, Contraband Detection and Personal Safety","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125750712","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 approach draws from two main areas: (1) computational fluid dynamic (CFD) simulations and (2) sensor placement algorithms. The main objective was to minimize detection time of a NBC sensor network for attacks on a generic urban environment. To this end we conducted simulations in such environments using thirty-three (33) unique attack locations, thirty-three (33) candidate sensor locations, prevailing wind conditions, and the properties of the chemical agent, chlorine gas. A total of ninety-nine (99) simulated attack scenarios were created (three sets of thirty-three unique attack simulations) and used for optimization. Simulated chemical agent concentration data were collected at each candidate sensor location as a function of time. The integration of this concentration data with respect to time was used to calculate the contaminant \"consumption\" of the network and the sensor placement algorithm, along with contaminant-level detection, minimized consumption to the network while also minimizing the number of sensors placed. Our results show how a small number of properly placed sensors (eight (8), in our case) provides the best achievable coverage (additional sensors do not help)","PeriodicalId":188809,"journal":{"name":"2006 IEEE International Workshop on Measurement Systems for Homeland Security, Contraband Detection and Personal Safety","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114462277","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}
