This invention relates to a radio fuze system and more particularly to a FMCW fuze system using multiple modulation of the RF carrier signal to achieve desirable absolute range cut-off whereby the fuze has ability to completely discriminate against targets that are greater than a desired fixed distance from the fuze and to See in-range targets in the presence of large return signals from out-of-range objects.
