Paper Abstract

This article analyses the motion detection results based on the Joint Transformer Correlator, and discusses the effect of shape, brightness and SNR of the correlation peak on the accuracy of results. The experiment shows that the shape of the correlation peak has more significant impact the motion detection than other factors, and the laser power level was relevant to shape, brightness and SNR of the correlation peak: the laser power level of input-image influences the graph of power spectrum, and changes the last shape and brightness of correlation peak image; the laser power level of the output-power spectrum affects the collected correlation pattern, and alters the shape and SNR of the correlation peak image. An optimal laser power of output power spectrum is found corresponding to a particular laser power of input image. In this paper, the correlation peak image quality evaluation function model is proposed and its effectiveness is verified by experiment data.
