摘要：

The correlation discrimination between the target and the reference in a joint transform correlator (JTC) deteriorates rapidly with an increase in the number of non-target objects in the input scene. The correlation peak in a JTC is increased significantly by updating the input plane information based on the correlation plane information. Simulation results are presented to verify the effectiveness of the proposed feedback scheme.
