Issue Date: | 2018 | Volume: | 2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC) | First Page: | 1 | Abstract: | In order to assess the polarimetric performance of phased arrays for radio astronomy, the Intrinsic Crosspolarization Ratio (IXR) can be adopted as a figure of merit. An innovative technique employing an Unmanned Aerial Vehicle (UAV) to measure the IXR of low-frequency instruments (VHF/UHF bands) has been recently exploited on a station of the Low Frequency Array (LOFAR) radio telescope. We present results from a spin flight measurement demonstrating 35 dB IXR in boresight, a value close to the performance limits of the current measurement system. | Conference Name: | 2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC) | Conference Place: | Meloneras, Spain | Conference Date: | 28 May-1 June, 2018 | URI: | http://hdl.handle.net/20.500.12386/29201 | URL: | https://ieeexplore.ieee.org/document/8471597 | ISBN: | 978-90-82598-73-5 978-1-5386-3764-7 |
