H1 line measurements were performed on 14.04.2019 using 4m parabol dish.
Antenna was tracking targets with 30s direction update rate.
LNA noise figure was approximately 0.4dB to 0.6dB
IQ-data was sampled using 2Ms/s rate with RF center frequency of 1420.400MHz
Resulting images were calculated for IQ-data of 200M samples.
Used FFT window length is 1024 samples.
Sun noise is used as reference for responce equalization. Sun noise level is approximately +13.0dB compared to cold sky.
