In the tactical arena, these functions range from surveillance and tracking to missile guidance, threat illumination, and kill assessment. The demands on waveform planning and energy management are heavy, however, and become even more so when the radar is used as a shared aperture, adding such functions as communications and navigation. The work described here represents research into waveform selection and energy management algorithms using an AI based weapons system simulation as a system testbed and analytical tool.<<ETX>>","PeriodicalId":297184,"journal":{"name":"Proceedings of IEEE National Telesystems Conference - NTC '94","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128351828","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 kinematic GPS landing system (KGLS) uses differential GPS carrier phase data to navigate landing aircraft. As the aircraft overflies a \"GPS marker beacon\" during its approach, the KGLS sensor uses beacon data to resolve the carrier phase integer ambiguity. This deterministic method provides centimeter-level accuracy and high reliability on every approach.<<ETX>>","PeriodicalId":297184,"journal":{"name":"Proceedings of IEEE National Telesystems Conference - NTC '94","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116068856","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}

Radar systems employing these high peak power sources must use ultrawide band antenna elements to efficiently meet system performance requirements. Unfortunately nearly all antenna elements that can meet the bandwidth requirements are undesirable for the airborne application because of their geometry and orientation necessary to utilize the maximum directivity. The equiangular spiral is a planar element which is suitable for the airborne application. This paper presents a heuristically derived expression for the transient radiation from this antenna and examines the performance of an ultrawide band active array composed of equiangular spiral elements, including beam forming and compensation of the waveform dispersion introduced by the spiral.<<ETX>>","PeriodicalId":297184,"journal":{"name":"Proceedings of IEEE National Telesystems Conference - NTC '94","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123004431","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 high stability of the synchronous pulses in the video signal makes it possible to find a range more accurately. The RMS error of 240 positions calculated every second on the ship navigating up Uraga Channel is 9.7 m longitudinally and 6.4 m latitudinally in reference to the positions by GPS. But we suspect that the GPS positions might have been modified by the Kalman filter, for the longitudinal error observed at a fixed point (Tokyo University of Mercantile Marine) is as small as 2.9 m.<<ETX>>","PeriodicalId":297184,"journal":{"name":"Proceedings of IEEE National Telesystems Conference - NTC '94","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124755417","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}
