The Japan Meteorological Agency has been upgrading its radar network to solid-state dual-polarization weather radars since 2016. This presentation introduces JMA’s operational experience with SSPA radar systems, including lifecycle sustainability, operational reliability, spectrum efficiency, and long-term stability of independent H/V transmitter architectures. Operational results demonstrate reduced failure rates, lower energy consumption, efficient spectrum utilization, and stable dual-polarization performance through continuous monitoring and calibration activities.
