Embodiment
[0062] During the shooting range test, the radar fuze is in working condition during the flight of the projectile. When the projectile falls and enters the working distance range of the radar fuze, the radar fuze continuously measures the target distance. When it reaches the set detonation distance value, the radar The fuze signal processor controls the missile-borne beacon to output the beacon signal, and the ground beacon receiver receives the beacon signal and stores it. When the projectile touches the ground, the beacon signal disappears, and the beacon received by the ground beacon receiver is measured The signal duration is used to calculate the actual flight distance of the projectile from the detonation point to the ground based on the projectile velocity at the set detonation distance value to calibrate the distance measurement error of the radar fuze to the ground.
[0063] As shown in Table 1 and Table 2, the projectile velocity when the projectile is detonated is calcu...

The invention discloses a proximity fuse distance speed measurement accuracy calibration device and method. The method includes the steps that a beacon emitting device is assembled on a cannonball, a fuse sends a triggering signal and a target velocity measured value to a beacon receiver at the designed detonation position, and the beacon receiver sends a radio signal of the corresponding frequency to ground receiving equipment; when the cannonball touches a target, a trigger is touched to control a signal generator to cut off the radio signal output; a beacon receiving device on the ground receives the radio signal sent by the beacon receiver on the cannonball; and by measuring the duration and frequency of the radio signal, the fuse distance and speed measurement accuracy can be calibrated. The calibration device is simple in design, the beacon emitting device on the cannonball can be realized easily, and the distance speed measurement accuracy of the proximity fuse can be calibrated accurately.
Description
Technical field [0001] The invention relates to a calibration device and a calibration method for the distance and speed measurement accuracy of a proximity fuze. Background technique [0002] With the changes in the scale, purpose and form of warfare, the application of precision guided weapons has become more and more extensive. Fuze, as the key component that sends out the final detonation signal in precision guided weapons, has received extensive attention at home and abroad. [0003] In proximity fuze technology, range control accuracy is an important performance index of proximity fuze. It is the guarantee for the control of the bomb point and the maximum damage effectiveness of the bomb. [0004] In the field shooting test to verify the performance indicators of the proximity fuze, the focus is on the accuracy and efficiency of the calibration fuze's range and speed measurement accuracy. At present, cameras, theodolites, infrared and other photoelectric equipment are commonl...
