A joint wavelet representation correlator is proposed as a new
architecture to combine wavelets and the joint transform
correlator. It performs wavelet representation preprocessing and
the correlation operation simultaneously. An intensity filter used
for wavelet representation is the power spectrum of the wavelet
function and can easily be synthesized and displayed. Computer
simulation shows that, as compared with previous joint wavelet
transform correlators, its discrimination capability is better and its
performance is more stable under input noise.
