Abstract: A method based on the combination of input plane Mathematical Morphology processing and power plane FAF processing is proposed to improve the recognition ability of JTC. First, theory of classical JTC is introduced. Second, aiming at its disadvantage, the combination of input plane morphology processing and power spectrum plane FAF processing is used to improve the correlation output performance of JTC. Finally, The parameter of the proposed JTC are analyzed. Experimental results show that when the correlation peak is very sharpness. The peak value is , which is higher than classical JTC. Performance of the combination based method is better than that of any single method based JTC. Target detection ability is also improved by using the proposed JTC.
