ABSTRACT:
1. In an ordnance projectile having a side-spray warhead with a static frentation velocity V.sub.FS, an ordnance fuze comprising: radar means for making measurements of range and sight angle of a target; sources of fixed voltages proportional to predetermined target coordinates Z.sub.1, Z.sub.2, and Z.sub.3, in a coordinate system that rides with the fuze, the fuze trajectory being in the plus-Z direction; means for obtaining three voltages proportional to r.sub.1, r.sub.2, and r.sub.3, where r.sub.1, r.sub.2, and r.sub.3 are the fuze-to-target distances when the target Z-coordinates are Z.sub.1, Z.sub.2, and Z.sub.3 respectively; means for obtaining a voltage proportional to V.sub.Z, where V.sub.Z is the rate of change of the Z-coordinate of the target with time; a source of fixed voltage proportional to said static fragmentation velocity V.sub.FS ; electronic computer means for solving the equation
