Embodiment Construction

[0034] The present invention will be described in further detail below with reference to the accompanying drawings.

[0035] combine figure 1 and figure 2 , a pre-measurement debugging device for a horizontal impact point passive acoustic positioning device, including a horizontal level 11, a vertical level 10, a cross laser 13, a laser rangefinder 9, a first debugging mechanism 15 and a second debugging mechanism 16. The horizontal impact point passive acoustic positioning device (MSI 541-475AS / A) includes sensor 1, sensor target surface 2, sound-absorbing material 3, beam 4, foot assembly 5 and protective cover 6, and a pair of can be symmetrically arranged at the bottom of beam 4. Adjust the foot assembly 5 to adjust the height of the beam 4 . The two sensor target surfaces 2 are symmetrically fixed on both ends of the beam 4 , and the target surfaces are perpendicular to the center line of the beam 4 in the longitudinal direction.

[0036] The longitudinal level 10 is ...

Abstract

The invention discloses a pre-test debugging device and method of horizontal impact point passive acoustic locating devices. The method is characterized in that the horizontal impact point passive acoustic locating devices are adjusted to be symmetrically distributed at the left and right of a trajectory line through devices such as tripods, centering rods, cross lasers, laser ranging instruments,and the like before testing; the horizontal impact point passive acoustic locating devices are perpendicular to the trajectory; the horizontal impact point passive acoustic locating devices are adjusted to be perpendicular to the trajectory according to the instruction output by the cross laser; whether the horizontal impact point passive acoustic locating devices are perpendicular to the trajectory is checked according to the output result of the laser ranging instrument. The method is simple, quick, and high in adjusting accuracy; the influence caused by the condition that the trajectory isnot perpendicular to the horizontal impact point passive acoustic locating devices on the locating accuracy can be removed; the method is suitably used for quickly adjusting the horizontal impact point passive acoustic locating devices to be perpendicular to the trajectory in a shooting site.

Description

technical field [0001] The invention belongs to a shooting target adjustment technology, in particular to a pre-test debugging device and a debugging method of a horizontal bullet impact point passive acoustic positioning device. Background technique [0002] In daily life, whether it is military industry or housing construction, etc., it is often necessary to adjust and measure the vertical. In the conventional vertical adjustment method of a horizontal line in a space and a straight line at a long distance, the measurement accuracy is usually low. In the use environment with high verticality requirements, the traditional method cannot meet the requirements. [0003] The horizontal impact point passive acoustic positioning device is a long-distance impact point real-time measurement device based on the shock wave signal generated by the high-speed projectile flight, which overcomes the complex operation of the traditional adjustment device, poor real-time performance and l...
