Accordingly, this paper presents an RF photonic feed system that is not only low profile, but offers scalability, wide operational bandwidth and multi-functionality. The approach uses a silicon micro-mirror for vertically feeding an optical fiber to a photodiode that is directly coupled to an antenna element in the phased array, which ensures low profile while preserving uniform beam quality.","PeriodicalId":190997,"journal":{"name":"2017 IEEE Avionics and Vehicle Fiber-Optics and Photonics Conference (AVFOP)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127049261","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}

Prather","doi":"10.1109/AVFOP.2017.8169764","DOIUrl":"https://doi.org/10.1109/AVFOP.2017.8169764","url":null,"abstract":"There is a growing need for RADAR systems to address short range sensing problems where standard electro-optic sensors are impeded. From convoy situational awareness to rotorcraft brownout, there are a growing number of military requirements to address degraded visual environments (DVE) where new solutions are needed to provide feedback to the operator in both manned and unmanned platforms. In such environments, millimeter-wave RADAR could potentially provide the necessary obscurant penetration for sensing in DVE, while maintaining sufficient resolution for operational awareness. However, to achieve real-time, low-latency sensing as required for most military applications, traditional raster swept beam approaches to spatial image formation cannot provide sufficient update rates for modest sensor field of regard and image resolution. Additionally, for such short range applications RADAR instantaneous bandwidths must be high to accommodate range resolutions commensurate with the application. One approach that is being taken to create more flexible RADARs for these and other applications, is to use active electronically scanned array (AESA) technologies combined with digital beamforming, where multiple beams can be analyzed simultaneously using digital processing techniques. However, such techniques require immense processing bandwidths as each beam to be formed in a given time window must be processed at a rate sufficient to encompass the instantaneous bandwidth of the RADAR return. As such, limits on processing power often limit the beam-bandwidth product that can be achieved using digitally beam formed arrays.","PeriodicalId":190997,"journal":{"name":"2017 IEEE Avionics and Vehicle Fiber-Optics and Photonics Conference (AVFOP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127552831","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 two most important features in most, if not all, deployable use cases are low propagation loss in fiber and wide bandwidth. Indeed, the massive fiber telecommunications industry was born from simultaneous utilization of these two advantages over other signal transport means. Avionic platforms present a host of analog signal paths but the lack of long transmission distances results in a difficult case for the insertion of microwave photonics technology. That is, the penalty in noise figure when converting between the electronic and optical domain is not recouped over typical avionic transmission distances. However, the last six years have seen a rapid increase in the study of microwave photonics techniques for radio frequency (RF) interference mitigation, which does not necessarily take advantage of the low loss in fiber. Military and commercial airborne platforms might benefit from such techniques. The state of the art in photonics for RF interference mitigation is reviewed here, suggesting that a layered approach utilizing photonics, analog electronics and digital electronics has strong potential.","PeriodicalId":190997,"journal":{"name":"2017 IEEE Avionics and Vehicle Fiber-Optics and Photonics Conference (AVFOP)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115780691","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}
