Abstract
System and modifications are presented which allow existing artillery and rtar projectile proximity fuzes to have a near-surface burst (NSB) option enabling low height of bursts ranging between one and three meters. The additional circuitry needed to implement this NSB into an existing fuze is a single operational amplifier. The velocity of the fuze is calculated by the micro-controller counting the number of Doppler cycles over a pre-determined sample period of time. Thereafter, using the fuze velocity, the delay time needed for a NSB detonation is computed.
