For distortion‐invariant radar image recognition with a hybrid electrical and optical signal processing technique, the design of the nonzero‐order joint transform correlator to achieve minimum average cross‐correlation energy has been studied. In this work, as we require the desired cross‐correlation peak to be real valued for all real‐valued training images, the optimized reference function will be real valued as well, although the reference function is optimized in the frequency domain with the method of Lagrange multipliers. © 2002 John Wiley & Sons, Inc.
