Abstract
This publication discloses a radiosonde system, a radiosonde system receiver and a signal processing method for use in a radiosonde system. The radiosonde system comprises at least one radiosonde (1) with means for acquisition of position and/or weather data and means for downstream transmission of the data over a radio-frequency path, signal capture means (2, 3) for reception of the weather and/or position data, and receiver means (4) for processing the received signals, the receiver means including RF circuit elements (11) for downconversion of the received signal frequency to a lower frequency known as the first intermediate frequency. According to the invention, the receiver means (4) include sampling means (12) performing sampling at the intermediate frequency, at least two digital mixer means (13) for selective filtration of desired frequency bands from the sampled signal, and processor means (14) for parallel signal processing at the desired frequency bands.
