The antenna elements are placed in a rectangular grid spaced at λ/2 apart at 14.5 GHz (Tx array) and 12 GHz (Rx array), and employ 16 silicon Tx- and Rx-only 8-channel beamformer chips to feed 2×2 dual-polarized antenna quads. The phased-arrays are assembled on a 4-layer printed circuit board (PCB) using only two Roger 4350B panels, mechanical drilled vias and simple fabrication, thus the ultra-low-cost designation. Both 64-element phased-arrays result in a scan range of $pm 60^{mathrm{o}}$ in the E-and H-planes with low sidelobes $< -15 mathrm{dB}$. The Rx phased-array has a 3-dB bandwidth of 650 MHz (11.4 - 12.05 GHz) and a cross-polarization level of $< -18 mathrm{dB}$. The Tx phased-array results in a measured EIRP of 48.7 dBm and 50.6 dBm at P1dB and Psat, respectively, per polarization, a 3-dB bandwidth of 750 MHz (13.75 -14.5 GHz), and low cross-polarization of −20.5 dB. To our knowledge, these Ku-band phased-arrays demonstrate state-of-the-art performance with ultra-low-cost for satellite communications or point-to-point communication systems.","PeriodicalId":410526,"journal":{"name":"2019 IEEE International Symposium on Phased Array System & Technology (PAST)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121272346","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}

Phased array radar (PAR) with solid-state amplifiers, attenuators and phase shifters uses additional signal processing schemes for achieving desired sensitivity, scan rate and data quality than in the case of a mechanically scanning radar that uses high-power klystron, magnetron or traveling wave tube transmitters. Active electronic scanning array (AESA) enables rapid scanning - the radar beam could be steered to any angular direction nearly instantly. Transmit and receive beam characteristics of AESA could be made independent of each other by an appropriate amplitude and/or phase weighting of the individual radiating element transmit and receive signals. Rapid steering of the antenna beam is suitable for beam multiplexing (BMX). BMX enables the collection of independent sample pairs of radar signals that reduce errors in radar measurements while providing rapid updates of scan volumes. Scan strategies for pencil beam and broad beam configurations are presented with regard to collecting reflectivity and radial velocity within a specified standard deviation of error. Beamforming radar architectures for pencil beam and broad beam configuration are described.","PeriodicalId":410526,"journal":{"name":"2019 IEEE International Symposium on Phased Array System & Technology (PAST)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125283984","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}

DoA angles of signals are estimated by processing the measurements from spatially distributed sensor arrays. In all these cases, conventional processing involves using linear processing to combine the measurements from the sensor elements of the spatial array. The DoA angular resolution is determined by the size of the spatial array. In this study, a multiplicative processing technique known as multiplicative array processing (MAP) is proposed to achieve fine angular resolution by using much smaller array sizes. Multiplicative processing of array measurements has the potential to achieve super-resolution capability where the effective resolution is commensurate with significantly larger array sizes. In this study, both simulations and experimental results are used to verify and validate the proposed multiplicative processing technique. Simulations indicate that for moderate to high signal-to-noise ratios, MAP performs as well as linear processing methods with much larger array sizes. MAP is applied to experimental measurements to verify and validate the effectiveness of the proposed technique with field data.","PeriodicalId":410526,"journal":{"name":"2019 IEEE International Symposium on Phased Array System & Technology (PAST)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134400208","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}

However, electronic scan angle dependent power and phase introduced by electronic beam steering as well as dual-polarization performance of phased array antennas is a challenge in developing polarimetric phased array weather radars. Front-X is an X-band dual-polarization phased array weather radar capable of both electronic and mechanical beam steering which can be used to validate electronic scan data against mechanical scan data. Additionally, the system can be used to explore and measure the differences between electronic and mechanical scan data. This paper presents a description of Front-X and an automated electronic scan calibration mode implemented in the system which generates corrections that account for power and phase differences between electronic and mechanical scan data. Finally, the system and the electronic scan corrections are demonstrated through a comparison of mechanical scan and electronic scan data, as well as a comparison to the co-located and proven CHILL X-band radar.","PeriodicalId":410526,"journal":{"name":"2019 IEEE International Symposium on Phased Array System & Technology (PAST)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133106537","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}
