Abstract
A desired range is selected prior to firing the projectile carrying the remote set fuze and after firing a Doppler radar provides Doppler pulses proportional to the relative velocity of the projectile. Constant frequency pulses are counted during a predetermined number of the Doppler pulses to provide an indication of the actual velocity of the projectile and the preselected range-to-function is achieved by means of a time-to-function adjustment to compensate for differences between the actual velocity and a predicted velocity. The adjusted time-to-function is transmitted to the remote set fuze in a coded form.
