PX-1000

Polarimetric X-band 1000
PX-1000 is a transportable, solid-state, polarimetric (independent H/V channels) radar providing educators and students with a unique and versatile approach to data collection for meteorological and radar engineering research.

System Overview

Designed, fabricated, and operated by ARRC, the PX-1000's dual-channel independent transmit chain opens up possibilities of novel waveform diversity for improving polarimetric radar quality. In addition to advanced signal processing developments such as spectral analysis and adaptive clutter filtering, real-time acquisition of time-series data also facilitates pulse compression development, for example. The PX-1000 is well suited for long-term field campaigns.
