| Abstract: | The principle of applying sampling averager to carrier free ultra wideband radars for moving target detection is analyzed. The working process of a sampling averager is deduced, and its mathematical model is proposed. Based on this model, a simulation is carried out, with the result that the time domain noise elimination method based on sampling and averaging can eliminate noise or high frequency jamming effectively. |
