It is demonstrated that very closely separated beams are possible if the transmitter is calibrated correctly in particular for demodulation of secondary beam signals. Excellent power and spectral efficiencies are demonstrated while also verifying the impact on the radar ambiguity function. The approach inherently adds a physical-layer level of communication security and is an attractive option for leveraging costly OTHR installations.","PeriodicalId":103360,"journal":{"name":"2023 17th European Conference on Antennas and Propagation (EuCAP)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123637599","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}

These may improve the reliability and robustness for position estimates in rural road scenarios compared to estimates from automotive sensor data only. Here, we report on the impact of multipath propagation and cellular network deployment geometry on estimation accuracy and the underlying optimization algorithm has been investigated.

The proposed approach will exploit a free moving probe system coupled to a laser-tracker and a software solution able to perform Near Field to Far Field transformation that includes also the probe-compensation and phase recovery in a direct way.

For tackling this highly nonlinear and ill-posed problem, it is required to combine different inverse profiling modalities. The proposed algorithm starts with using the total variation minimization (TVM) method to locate the objects and roughly estimate their borders. Then, an iterative multi-scale approach (IMSA) is implemented to confine the investigation domain (ID) to the detected objects regions, step by step. Using this approach, the resolution can be enhanced without increasing the number of unknowns. As the inverse solver, the robust stochastic optimization technique of Covariance Matrix Adaption Evolution Strategy (CMA-ES) is utilized in each step. The presented numerical results indicate the efficiency of the proposed algorithm in quantitative profiling of multiple objects, using limited amount of data.","PeriodicalId":103360,"journal":{"name":"2023 17th European Conference on Antennas and Propagation (EuCAP)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114812225","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}

By dividing the patch cells into fractional pieces, the impedance bandwidth of the proposed antenna is improved. In the proposed neural network, the input data is the target reflection coefficients of the metasurfaces antenna, and the neural network predicts the geometry of patch pieces that satisfy the target performance. A prototype antenna is fabricated and measured to verify the design strategy.
