La M734 es un tipo de espoleta multiopcional para proyectil de mortero que usa técnicas de onda de frecuencia modulada continua (FMCW) direccional de búsqueda Doppler (DDR) y es resistente a contramedidas electrónicas diseñadas para generar estallidos prematuros. La energía eléctrica es entregada a la espoleta por un alternador-generador movido por aire . (es) The M734 multi-option fuze is a rangefinder and collision detection system used on 60mm, 81mm, and 120mm mortar shells as a trigger to detonate the shells at the most damaging heights of burst when combating four types of battlefield threats: * The rangefinder is a Doppler radar using FMCW technology to emit a radar signal and can be set to trigger two types of air-bursts, one being a near surface burst to combat standing targets and the other being a higher proximity burst downward onto prone or dug-in targets. * The collision detection portion of the fuze consists of two mechanical devices, one being a quick response electric inertial switch for a burst upon impact with a target, such as a vehicle, and the other being a slow response mechanical detonator that allows shell penetration, such as through a forest canopy, before detonating. This integration of four functions into a single fuze reduces the logistics and cost to support mortar crews on the battlefield.
