【摘要】 <正> A detailed theoretical analysis of strip-coupled LiNbO3/p+ n diode surface acoustic wave (SAW) memory correlator in the parametric mode is presented. The influence of some important factors on correlation output is analyzed and calculated, including the amplitudes of reference, read and write signal, duration of write signal and doping density of the diode array. The conclusions can be employed for the design of improved strip-coupled SAW memorycorrelators.
