Data logger for radar vegetation clutter collection

摘要

A stand-alone module for data collection and signal processing in multi-channel radar receiver is considered. Technical requirements, module structure, operating principles, used parts are discussed in order to obtain low noise data record, long battery lifetime operation and small size. The equipment is designed for vegetation clutter experimental measurements in bistatic radar configuration. The module provides data collection at four different radar carrier frequencies in VHF and UHF bands simultaneously in eight I/Q channels with 24-bit ADC resolution and up to 200 Hz sampling frequency in each channel.
