description The invention provides an automatic gain control method based on time division signal power statistical model, comprising the steps that through counting power by segment, the whole pulse period can be covered, and the maximum power within the period can be selected, and it can be ensured that a strong signal power is input in an AGC filtering loop; the maximum power is averaged, and extraordinarywaving of power observed quantity caused by the fading of the depth of foundation signal can be removed; adjusting amount can be obtained through low-pass smoothing, and the adjusting dynamic can beguaranteed not to be excessively large or frequent, causing losing lock of the rear-end loop; the adjusting amount is compared with a threshold, and if the adjusting amount exceeds the threshold, theAGC is ordered to adjust output power. The invention is advantageous in that the power of strong time division signal can be accurately calculated, and thereby the AGC output will not be overloaded, and strong signal will not b
