Dear colleagues.
please help in solving the actual problem:
Our company operates in the field of space communications .
For reception and transmission of signals via satellite is used parabolic antenna with a diameter of 12 m
Frequency of received signal is 4000 MHz.
The receiver is a Low noise amplifier with an effective temperature of noise 40 K.
At times, the noise level in the receiving circuit increases sharply in 8 times, then after some time, it returned to normal.
The same antenna near shows no increase in noise.
What might be the cause of the noise ?
How can we remove it ?
