 ===== Principle =====
-The NYRAD35 is a dual-polarization simultaneous transmission and simultaneous reception (STSR; also referred to as hybrid-mode, or STAR, simultaneous transmission and reception) radar, with elevation-scanning capabilities. The scanner can perform full 180° scans in elevation and is operated at a constant azimuth of approximately 27°, i.e., along the north-north-east to south-south-west direction. STSR radars receive at horizontal and vertical polarization but transmit a signal that is linearly polarized at 45° direction between vertical and horizontal directions. This allows both for linear depolarization ratio (LDR) observations in zenith and typical dual-polarization variable observations at low elevations, such as differential reflectivity (ZDR) or specific differential phase (KDP). Matching Ka- and W-band observations at zenith allows calculation of the DWR to obtain information on the characteristic size of the ice particle population.
