This has been spurred in part by successful demonstrations of remote sensing of human physiological motion using radar, for healthcare applications. However, most reported physiological radar results have focused on the use of continuous wave radar operating between the 2.4 GHz up to 24 GHz, to monitor a single, isolated subject. There is a recent paradigm shift in the automotive radar industry towards the use of W-band frequency modulated continuous wave radar. This research investigates the feasibility of extracting vital signs information for both single and multi-subject scenarios, utilizing a newly developed 76–81 GHz FMCW single channel architecture automotive radar. Chirp parameters and signal processing steps were developed to extract phase information for signals reflected from tiny movement of a subject's chest surface. Beam steering techniques were used to isolate the respiratory signatures for individual subjects from radar signals reflected simultaneously from multiple subjects. Experimental results showed that independent respiratory signatures could be isolated and measured for subjects separated by a 30° angular discrimination limit.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"66 1","pages":"783-786"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82236742","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 oscillator core is based on the complementary cross-coupled topology. The SRO is capable of recovering the phase of a very small input signal and regenerate it in a much greater output signal. The circuit is fabricated in a 22-nm FD-SOI CMOS technology over a total chip area of 0.49 mm2. Measurement results have shown that the minimum input power level required for a phase-coherent output is -42 dBm. The SRO delivers a maximum output power of 1.5 dBm, which corresponds to a regenerative gain of up to 43.5 dB. The oscillation frequency of the SRO ranges from 55.6 GHz to 61.5 GHz, which results in a tuning range of 10%. With a DC power consumption of only 10 mW the circuit demonstrates a power efficiency of 14.1%, which is the highest reported efficiency by a mm-wave SRO to date. The oscillator achieves a maximum switching rate of 10 GHz, which is, to the best knowledge of the authors, the highest reported to date. This makes the presented circuit suitable for highly-efficient high-data-rate communication.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"31 1","pages":"349-352"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89615181","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}

Hereby, close adjacent targets can be distinguished from each other. Usually those systems are designed at very high frequencies around 100 GHz and above because here, sensors with high bandwidth can be designed with less effort but signal handling, antenna design and high output power is more difficult and harder to achieve at those frequencies. In this work, a modern SiGe BiCMOS process was used to develop an ultra-wideband (UWB) bistatic FMCW radar MMIC with over 40 GHz continuous bandwidth below 60 GHz. This MMIC is the key component of the presented ultra-wideband FMCW radar system. The high bandwidth is generated by down-converting two high-frequency VCOs at around 100 GHz but merely the down-converted signal below 60 GHz of both VCOs which is easier to handle leaves the MMIC. The output signal provides a frequency range which corresponds to the sum of the bandwidths of both VCOs. This leads to a radar system that achieves ultra-wide continuous bandwidth at moderate frequencies for high spatial resolution.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"5 1","pages":"1255-1258"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90181125","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}

Based on a unified system model for fully-digital and hybrid MU-MIMO transmitters, the requirements and difficulties of data acquisition for MU-MIMO DPD are outlined first. A versatile OTA data acquisition technique, featuring a multi-observation forward modelling procedure, is thereby developed to obtain power amplifier (PA) output without interrupting the operation of the MIMO transmitters. By using this method, the output of each PA can be reconstructed instead of directly measuring each PA's output, even when the output signals of PAs are correlated. DPD can therefore be effectively constructed to mitigate the distortion. Experimental results demonstrate that the proposed approach can accurately estimate each PA output and linearize all PAs in the array.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"12 1","pages":"845-848"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84806082","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}
