Defense weapon systems also need to detect and then identify threats also using sensors. One important class of sensors is radar systems that are very efficient for all weather detection. High frequency radars can produce high quality images with very complex features such as dihedral and corner reflector high scattering contributors, shadows and layover effects. Besides, image quality is very dependent on the carrier velocity and trajectory. Such sensors systems are so complex that they need simulation to be tested in a large variety of operational conditions. This paper presents a state-of-the-art solution, called SE-Workbench-RF, for generating raw data dedicated to radar simulation based on the exploitation of synthetic environments, which means physical modelling of targets and backgrounds (terrains, buildings, vegetation and other entities). The paper gives an overview of the models and their implementation in SE-RAY-EM, which is the rendering module of SE-Workbench-RF, including specific features related to radar simulation in the maritime environment with targets moving on the dynamic sea surface. Several technical topics are also discussed, such as the rendering technique (ray tracing vs. rasterization), the implementation (CPU vs. GP GPU) and the tradeoff between physical accuracy and computational performance.","PeriodicalId":155427,"journal":{"name":"2019 20th International Radar Symposium (IRS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130637751","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}

This lead to impact on applications such as Extended Object Tracking operating on the radar detection level data and this problem has to be investigated.

Due to the continuous improvement of the measurement accuracies new fields of applications arise for radar like free space detection or localization. For example, the synthetic aperture radar (SAR) makes it possible to improve the azimuth resolution by exploiting the driveway. The quality of the image, however, depends significantly on the accuracy of the motion estimation of the antenna. Current researches in this area use the vehicle odometry to estimate the antenna position. The following paper investigates an approach to carry out synthesis of an artificial aperture by means of radar-based motion estimation.","PeriodicalId":155427,"journal":{"name":"2019 20th International Radar Symposium (IRS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116916717","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}
