Both numerical and experimental results show an enhancement of the side lobe values with respect to previously analysed resonant-slot-fed antennas despite the experimental response deterioration due to manufacturing inaccuracies.","PeriodicalId":171460,"journal":{"name":"2018 15th European Radar Conference (EuRAD)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123180614","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}

In order to simulate different outdoor conditions, mainly temperature and lighting, the whole setup, which includes the grapevine and the measurement system, has been settled inside a growth chamber. Fluctuations of lighting conditions, temperature and irrigation have been correlated with variations of the signal power reflected on the trunk using both time domain broadband measurements and, magnitude and phase frequency domain narrowband measurements. The innovative setup enables the achievement of more reliable and accurate results when external conditions vary. Finally, the results have been contrasted, with high level of correlation, with long-established techniques using a dendrometer and a humidity probe.","PeriodicalId":171460,"journal":{"name":"2018 15th European Radar Conference (EuRAD)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122930366","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}

Compared to image based techniques, it does not suffer from inaccuracies in the case of multiple interactions. At the same time, very general measurement setups are possible without introducing severe truncation errors and the resulting field transformation problem can still be solved efficiently, due to the implementation based on propagating plane-wave expansions of the Green’s function. The theory of the algorithm is first outlined and then validated using simulated near-field and far-field data.","PeriodicalId":171460,"journal":{"name":"2018 15th European Radar Conference (EuRAD)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125701303","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}

Current multistatic radars operate independently and heavy synchronization algorithms are required to permit the fusion of the collected data.

Here, for the first time, these systems are studied considering the effect of the main system parameters and noise sources.

Results are shown for 2D reconstructed sliced images of the breast taken for four different transmitters.

The key issue is the stable radiation pattern with flat gain characteristic along the whole frequency bandwidth, which is very advantageous for the targeted radar applications. The antenna is taped out with the new high resolution multi-layer PCB technology, called \"Any-Layer PCB\". This technology provides the possibility to stack micro-vias in PCB boards and reduce the fabrication cost compared to other multi-layer technologies in mm-wave bands. With this feature, the width of the array has been compacted with 17.2%, which leads to a higher side lobe suppression and an enhancement of the field of view in radar applications. A combined impedance and 3-dB gain band width of 9.6% is achieved. The gain and SLL are 13.52 dB and −14 dB at 79 GHz, respectively.","PeriodicalId":171460,"journal":{"name":"2018 15th European Radar Conference (EuRAD)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131515914","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}
