摘要：

A digital simulation of frequency limitation and saturation effects in the power spectrum of a real time joint transform correlator (JTC) has been carried out. The results of optical image recognition using a real time JTC with a liquid crystal television to display the power spectrum are compared with the simulation, for different images. The resemblance between optical and simulated results confirms the good agreement obtained by the analysis.
