In this paper, the passive UAV synthetic aperture radar (SAR) system with geosynchronous illuminator (PUAV-SAR) is studied. The UAV platform passively reuses the backscattered signal of a GEO-SAR, and achieves bistatic imaging and data communication. Firstly, the aperture and path design problem is modeled as a constrained multiobjective optimization problem. Then, a path design method is presented to generate a UAV path with optimized mission performance. Numerical simulations are conducted to verify the effectiveness of the proposed method.","PeriodicalId":104242,"journal":{"name":"2022 IEEE USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133226984","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}

Low power and cost-efficient wireless transceivers are currently being employed for implantable medical devices (IMDs), in addition to military and civilian applications such as monitoring, surveillance, and home automation. The major goal of this paper is to do a thorough and realistic link budget analysis for an implantable wireless transceiver operating in the 3–5 GHz ultrawideband frequency with a link distance of 2 m (which includes 10 mm of brain tissue layer and 1.99 m of air medium), data rate of 100 Mbps with On-Off keying (OOK) modulation, and a minimum receiver sensitivity of −58.01 dBm. The proposed power budget analysis is particularly well suited for distributed brain implant applications as it models the path loss including the tissue layer without compromising the spectrum regulation imposed by the Federal Communications Commission (FCC) for UWB communication.","PeriodicalId":104242,"journal":{"name":"2022 IEEE USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130526532","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 receiver operates at 5.8 GHz with a continuous wave (CW) signal. The system, which operates as a doppler-RADAR, was simulated, fabricated, and characterized and measurements of respiration rate and heart rate are performed. The concept relies on the detection of the phase of the received signal which changes due to the physical movement of the chest and nearby biological tissues. This is performed with the FPR, the associated calibration, and the signal processing procedure. Accurate measurements of respiration and heartbeat frequency as well as their time domain waveforms are obtained. Additionally, a microstrip and a Vivaldi antenna were also used which helped achieve longer distance monitoring.","PeriodicalId":104242,"journal":{"name":"2022 IEEE USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133527441","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}
