Abstract
An algorithm for single pulse chirp signal detection at low signal/noise ratios is proposed. The proposed detection algorithm is based on the cross-correlation of the input chirp pulse and its copy subjected to a frequency shift. As a result of the proposed transformation, a gain in the signal/noise ratio is achieved, which allows the effective use of threshold detection.
