This paper presents a theoretical framework for determining the miss distance of fragmentation projectiles equipped with Doppler proximity fuzes, expressed as a function of specific structural parameters. The analysis considers both the spatial offset between the antenna and the warhead detonation center (Δr) and the angular distribution of fragments, which together govern the effective lethality zone and detonation timing. The mutual influence of parameters such as the antenna–warhead separation, the projectile-target impact angle, the miss phase, and the mean fragment dispersion angle on the resulting miss distance is quantified. Nu-merical analysis confirms that Δr exerts the dominant influence on miss distance, while angular parameters play secondary roles. The findings highlight the critical role of Δr in realistic projectile-fuze configurations and provide a solid basis for selecting suitable structural parameters for various types of shells employing non-contact fuzes during the design process.
