Abstract :
The proposed approach uses two types of correlator. The first is a correlator using DFT to detect the positions of peak values, while the second is a correlator using the discrete rotational Fourier transform (DRFT) to display the correlated images. The purpose of this scheme is to recognise multiple different targets simultaneously
