Efficiency of moving target indication systems when using fast acting automatic gain control
Abstract
The use of a limiter to reduce the dynamic range of input signals causes significant reduction of the periodic correlation coefficient for clutter and consequently lowers the effectiveness of MTI radars. The present work evaluates the substitution of the limiter by a fast AGC system relative to the effect this would have on the periodic correlation coefficient for clutter consisting of a narrow-band random stationary normal process. Results show that the drop in MTI system effectiveness is much lower when a fast AGC system is used instead of a limiter for signal normalization.
