The scanning patterns are selected to be suitable for next generation systems based on MEMS mirrors and Optical Phased Arrays alike. Two different wavelengths are compared. Based on the current version of the laser safety standard IEC 60825-1 the maximum energy is determined for the two patterns and two wavelengths. For a wavelength of 1550 nm no differences are revealed. At 905 nm, patterns allowing a large spatial and temporal separation between subsequent measurements are favored.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134400697","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 the first section is adopted the basic taxonomy of attribute identification in accordance with the standards of STANAG 1241 ed. 5 and STANAG 1241 ed. 6 (draft). These standards provide the following basic values of the attribute identifications: FRIEND, HOSTILE, NEUTRAL, UNKNOWN and additional values: ASSUMED FRIEND and SUSPECT. The last values can be interpreted as a conjunction of basic valus. The basis of theoretical considerations is the Dezert-Smarandache theory of inference. The following combining rules are presented: the classical and hybrid Dezert-Smarandache rules and the Proportional Conflict Redistribution #5 (PCR5).The basic belief assignment for primary and secondary radars has been taken from [14]. In the next section rules of determining attribute information by ESM sensor equipped with the data base of radar emitters are presented. The emitter DB has a lot of records for any class of emitter. Signal parameters vector recognition is based on finding the nearest center of emitter parameters cluster. The basic belief assignment (bba) of different attribute identification values for ESM sensor has been defined. Each sensor report sent to the fusion information center contains a vector of belief mass of attribute identification. Results of the PCR#5 sensor information combining method are presented in the final part of the paper. At the end of the paper conclusions are given. They confirm the legitimacy of the use of the Dezert-Smarandache theory into information fusion for primary radars, secondary radars and ESM sensors.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133993480","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}

Aim of the proposed estimation strategy is to provide 2D passive sensors, which measure only bistatic range and Doppler, with target height estimation capability via the simultaneous exploitation of multiple FM transmitters (88–108 MHz). Results achieved with simulated and real passive data demonstrate that it is possible to estimate the target height with an accuracy of few hundreds of meters even if the precision of bistatic range measures is poor (up to one kilometer); this is possible thanks to the bistatic Doppler measures that show a standard deviation of few or fraction of Hz.

The technique applies to scenarios where targets can be modeled as having a few predominant scatterers, such as some made man-made targets. The basic idea is to change the signal used as reference for detection in such a way that it is adapted to the predominant scatterers of the targets. When compared with another recently published technique the obtained detection gains are similar. However, in contrast to that, the proposed technique shows the additional advantage that the received data is still useful for further processing.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"352 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114827818","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}

With the evolution of radar hardware, the range resolution of radar is often much smaller than the size of the radar targets which cannot be treated as point targets any more. In the literature, various electromagnetic field simulations or ray tracing approaches exist. However, these approaches are often computationally complex and a sound understanding of the algorithms is required. In this paper, we present a simple radar simulation framework for the simulation of 3D objects larger than the radar range resolution. For this purpose, we use the existing ray tracer of the graphic simulation program Blender and process the rendering results of Blender to simulate radar raw signals.","PeriodicalId":430241,"journal":{"name":"2017 18th International Radar Symposium (IRS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125926405","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 causes a significant delay between the actual transmit-receive event and the appearance of detection and/or estimated parameters of an object at the processor output. The paper is aimed at assessing the influence of such latency on the tracking error in the case of rotating array radar.
