AUTOMATISK FORSTERKNINGSREGLERKRETS FOR EN PULSRADARAPPARAT |
摘要 |
Disclosed is an automatic gain control (AGC) circuit for an IF amplifier utilized in the receiver of a pulsed radar. The AGC circuit is provided with a noise measuring circuit for determining the minimum value of a number of average noise levels over corresponding time intervals of given short duration within the length of time for the range-independent RF signal amplification in the pulse repetition period. Such a noise level, based on the minimum value, can be considered to be least influenced by rain clutter. The IF amplifier is adjusted to this noise level. |
