DUAL-POLARIZATION RADAR DEVICE AND RADAR SIGNAL PROCESSING METHOD

摘要

A linear-depolarization ratio calculator (12) is configured so as to determine a radar reflectivity factor Z_hh in transmission of a horizontally polarized wave and reception of a horizontally polarized wave, the radar reflectivity factor being a reflected wave intensity after integration of a reflected wave intensity V_hh(n) calculated by a reflected-wave intensity calculator (11), and a radar reflectivity factor Z_vh in transmission of a horizontally polarized wave and reception of a vertically polarized wave, the radar reflectivity factor being a reflected wave intensity after integration of a reflected wave intensity V_vh(n+2), and calculate a linear depolarization ratio LDR_vh which is the ratio between the radar reflectivity factor Z_hh and the radar reflectivity factor Z_vh. As a result, even when three types of polarized-wave transmission/reception processing elements are repeatedly performed, the linear depolarization ratio LDR_vh can be calculated.
