Research on Looking-forward Altimetry Strategy for Missile-borne Monopulse Detector

The height of missile needs to be acquired in real time to perform the preset combat missions for the new generation optional burst height proximity fuze. A forward-looking altimetry strategy for missile-borne monopulse detector is proposed, which achieves high precision and fast terrain elevation calculation on the missile-borne platform with high real-time requirements. An altimetry model of missile-borne detector is established, and the altimetry algorithm of missile-borne monopulse detector is deduced from the theory of monopulse ranging. The altimetry algorithm is verified by simulation and field test. The experimental results show that the monopulse altimetry system can meet the precision requirement of the new optional burst height proximity fuze for burst height. The average error of simulation altimetry is 7.8%, the altimetry error of suspension flight test is less than 2.5 m, and the overall response time can meet the needs of the missile-borne platform.
