%X Generally, Doppler fuze can only estimate actuation delay-time with a limited precision. As an improvement, imaging fuze can estimate actuation delay-time more precisely with the available two-dimensional image of the target. In this paper, imprecision of actuation delay-time estimation with Doppler fuze is first analyzed theoretically in brief. Secondly, feasibility analysis and theoretical model of imaging fuze are described, in which a criterion is established for the actuation delay-time based on the image, and then an image based gray-value weighted least square (GWLS) algorithm is presented to calculate actuation delay-time of the imaging fuze. Finally, a simulation model of missile-target near-field encounter is established. Simulation results indicate that actuation delay-time of the imaging fuze is estimated more precisely than by the Doppler fuze.<br>Generally, Doppler fuze can only estimate actuation delay-time with a limited precision.
