Abstract
The invention discloses a ground combined test device of a directional fuze warhead total system and a test method thereof. The device comprises a missile launcher, a fuze, a detonating system, a high-speed camera, a speed measuring target and a positioning target. The missile launcher launches missiles. The fuze is positioned at the side of a missile flying trajectory for detecting the missiles to obtain detecting wave beams and processing the detecting wave beams to obtain a detonating instruction. The detonating system receives the detonating instruction of the fuze for selecting a corresponding detonating direction to output and detonate according to the detonating instruction. The high-speed camera captures flying attitudes of the missile passing by the fuze. The speed measuring target measures the missile flying speed in the missile flying trajectory. The positioning target is positioned at the tail section of the flying trajectory for recording the missile targeting attitude. The device can check the direction identifying precision of the fuze and the ignition transfer matching performance of the detonating system, and synchronously records the ignition transfer delay of each stage of ignition sequences, so that the fit condition between the directional fuze and the detonating system can be checked.
