Utilizing a high contrast liquid crystal light valve (LCLV) to perform joint power spectrum nonlinear processing, real time nonlinear joint transform correlation is implemented. Using this nonlinear joint transform correlator (NLJTC) as the key part, a hybrid adaptive moving object tracking system is then constructed. Experimental researches about continuously varying moving objectson scale, rotation, etc , have been accomplished. In this paper, the method of implementing nonlinear joint transform correlation and the principle of adaptive moving object tracking are described, experimental results are also given.
