Dealiasing doppler spectra in meteorological radars
A method of dealiasing of Doppler spectra is proposed. The method is based on the fact that overlaid spectral components of the received signals are statistically independent, and that there is no overlay in range. For implementation of the method, the radar is supposed to transmit trains of pulses...

oai:ri.kharkov.ua:article-4172012-11-04T11:41:07Z Dealiasing doppler spectra in meteorological radars Восстановление допплеровских спектров в метеорологических радиолокаторах Sosnytskiy, S. V. A method of dealiasing of Doppler spectra is proposed. The method is based on the fact that overlaid spectral components of the received signals are statistically independent, and that there is no overlay in range. For implementation of the method, the radar is supposed to transmit trains of pulses with two or more pulse repetition frequencies. In contrast to usual dual-PRF techniques, it does not require the Doppler spectrum to be narrow. The method is validated on experimental data from a meteorological radar, the dealiased spectra are compared with those measured directly at higher pulse repetition frequency. Предложен метод восстановления допплеровских спектров. Метод основан на том, что наложенные спектральные ком- поненты принятых сигналов статистически независимы, а так- же на отсутствии наложений сигнала по дальности. Для реа- лизации метода локатор должен излучать пачки импульсов на двух или более частотах повторения импульсов. В отли- чие от обычных методов, основанных на двух частотах по- вторения импульсов, он не требует узости допплеровского спектра. Метод проверен на экспериментальных данных, записанных метеорологическим локатором; восстановленные спектры сравниваются со спектрами, измеренными на боль- шей частоте повторения импульсов.
