Description

Our Pulsed Weather Radar operates in the L-band (1669–1681 MHz) and employs single-channel monopulse phase-comparison technology to deliver high-precision atmospheric detection from ground level to 30 km altitude. Designed and built for the China Meteorological Administration (CMA), the system combines pulse-based ranging with angular tracking to measure wind direction, wind speed, temperature, pressure, and humidity across multiple atmospheric levels - providing meteorological stations with accurate, automated upper-air observation data.

Key Features

L-band pulsed architecture - operates at 1669–1681 MHz with pulse-based transmission, enabling precise ranging from 100 m to 200 km within a single coherent system
Single-channel monopulse phase-comparison technique - first-of-its-kind implementation in the L-band; delivers angular tracking accuracy of ≤ 0.08° RMS at elevation angles above 6°
Close-range precision ranging - short-range distance measurement technology provides accurate ranging within 100 m, covering the full detection envelope from near-field to 200 km
Full hemispheric coverage - 360° azimuth rotation and −2° to +92° elevation sweep ensure continuous balloon tracking from launch to maximum altitude
Fully automated operation - radar tracking, data acquisition, meteorological data processing, and message compilation are all performed without manual intervention
Radio theodolite functionality - angular measurement capability equivalent to a dedicated radio theodolite instrument
