Features of Signals Reception and Processing at the Kharkiv Incoherent Scatter Radar

The features of reception and transformation of the incoherent scatter signal as well as digital processing signals extracted at low and intermediate frequencies are considered. The system for recording and processing signal at intermediate frequency is proposed. The justification for the choice of its frequency multiplier unit is adduced for forming ADC reading pulses that rigidly linked to intermediate frequency. The developed system allows employ algorithms that adapted to the altitude range under study and ionospheric plasma conditions.
