A millimeter wave detector is applied to a novel large dynamic optional burst height proximity fuze, and it provides a higher measurement precision. In this paper, the height measurement model of the missile-borne millimeter wave detector is established to provide a theoretical basis for the measurement of burst height. A burst height measurement method based on the change rate of voltage and Doppler shift has been proposed. Compared with the traditional millimeter wave fuze continuous wave height measurement system, the proposed method shows higher measurement accuracy and faster computing speed. Through a series of digital simulation experiments, the proposed method allows the height to be estimated when the terrain reflectivity is unknown.
